What luck has gave you will probably leave you.

While most of us are comfortable acknowledging that luck plays a role in what we do, we have difficulty assessing its role after the fact. Once something has occurred and we can put together a story to explain it, it starts to seem like the outcome was predestined. Statistics don't appeal to our need to understand cause and effect, which is why they are so frequently ignored or misinterpreted. Stories, on the other hand, are a rich means to communicate precisely because they emphasize cause and effect.

What was a shadow, after all, but a shape in the moving world reduced to a projection of possibilities?

You have a very high probability of your quote and your name being distributed, posted, and shared around the world!

Digital television is no longer a probability, it is a certainty.

A person who is psychic is following a line of probability to see a probable future; but it can change. Another causal fact will interfere and that future won't happen.

Yet Laplace had built his probability theory on intuition. As far as he was concerned, "essentially, the theory of probability is nothing but good common sense reduced to mathematics. It provides an exact appreciation of what sound minds feel with a kind of instinct, frequently without being able to account for it.

Do not expect to arrive at certainty in every subject which you pursue. There are a hundred things wherein we mortals. . . must be content with probability, where our best light and reasoning will reach no farther.

Fear was stronger than the calculation of probabilities.

Embrace the probability of your imminent death....and know there is nothing i can do to save you.

Generally, a betting system for which each wager depends only on present resources and present probability of success is known as a Markov betting system.

History cannot be reduced to a set of statistics and probabilities.

If a lack of empirical foundations is a defect of the theory of logical probability, it is also a defect of deductive logic.

Death is always a constant possibility and probability and of course an inevitability, as well.

Fourth Law of Thermodynamics: If the probability of success is not almost one, then it is damn near zero.

Let probability and sample size do the heavy lifting.

It is dangerous to attach probability zero to anything other than a logical impossibility.

The probability of success is difficult to estimate; but if we never search the chance of success is zero.

motivation is highest when the probability of success is 50 percent: We don't get involved if the task is too easy or too hard.

Psychology helps to measure the probability that an aim is attainable.

We often regret we did not do otherwise, when that very otherwise would, in all probability, have done for us.

When asked what he meant by a miracle: Oh, anything with a probability of less than 20%.

Money isn't always the best motivator. If you leave a $50 check after dinner with friends, you don't increase the probability of being invited back.

Such an event is probable in Agathon's sense of the word: 'it is probable,' he says, 'that many things should happen contrary to probability.'

The province of faith begins where probabilities cease and sight and sense fail.

When a coincidence seems amazing, that's because the human mind isn’t wired to naturally comprehend probability & statistics.

4. Religion. Your reason is now mature enough to examine this object. In the first place, divest yourself of all bias in favor of novelty & singularity of opinion... shake off all the fears & servile prejudices, under which weak minds are servilely crouched. Fix reason firmly in her seat, and call to her tribunal every fact, every opinion. Question with boldness even the existence of a God; because, if there be one, he must more approve of the homage of reason, than that of blindfolded fear. You will naturally examine first, the religion of your own country. Read the Bible, then as you would read Livy or Tacitus. The facts which are within the ordinary course of nature, you will believe on the authority of the writer, as you do those of the same kind in Livy and Tacitus. The testimony of the writer weighs in their favor, in one scale, and their not being against the laws of nature, does not weigh against them. But those facts in the Bible which contradict the laws of nature, must be examined with more care, and under a variety of faces. Here you must recur to the pretensions of the writer to inspiration from God. Examine upon what evidence his pretensions are founded, and whether that evidence is so strong, as that its falsehood would be more improbable than a change in the laws of nature, in the case he relates. For example in the book of Joshua we are told the sun stood still several hours. Were we to read that fact in Livy or Tacitus we should class it with their showers of blood, speaking of statues, beasts, &c. But it is said that the writer of that book was inspired. Examine therefore candidly what evidence there is of his having been inspired. The pretension is entitled to your inquiry, because millions believe it. On the other hand you are astronomer enough to know how contrary it is to the law of nature that a body revolving on its axis as the earth does, should have stopped, should not by that sudden stoppage have prostrated animals, trees, buildings, and should after a certain time have resumed its revolution, & that without a second general prostration. Is this arrest of the earth's motion, or the evidence which affirms it, most within the law of probabilities? You will next read the New Testament. It is the history of a personage called Jesus. Keep in your eye the opposite pretensions: 1, of those who say he was begotten by God, born of a virgin, suspended & reversed the laws of nature at will, & ascended bodily into heaven; and 2, of those who say he was a man of illegitimate birth, of a benevolent heart, enthusiastic mind, who set out without pretensions to divinity, ended in believing them, and was punished capitally for sedition, by being gibbeted, according to the Roman law, which punished the first commission of that offence by whipping, & the second by exile, or death in fureâ. ...Do not be frightened from this inquiry by any fear of its consequences. If it ends in a belief that there is no God, you will find incitements to virtue in the comfort and pleasantness you feel in its exercise, and the love of others which it will procure you... In fine, I repeat, you must lay aside all prejudice on both sides, and neither believe nor reject anything, because any other persons, or description of persons, have rejected or believed it... I forgot to observe, when speaking of the New Testament, that you should read all the histories of Christ, as well of those whom a council of ecclesiastics have decided for us, to be Pseudo-evangelists, as those they named Evangelists. Because these Pseudo-evangelists pretended to inspiration, as much as the others, and you are to judge their pretensions by your own reason, and not by the reason of those ecclesiastics. Most of these are lost... [Letter to his nephew, Peter Carr, advising him in matters of religion, 1787]

You aren't your past, you are probability of your future.

A distinguished writer [Siméon Denis Poisson] has thus stated the fundamental definitions of the science: 'The probability of an event is the reason we have to believe that it has taken place, or that it will take place.' 'The measure of the probability of an event is the ratio of the number of cases favourable to that event, to the total number of cases favourable or contrary, and all equally possible' (equally like to happen). From these definitions it follows that the word probability, in its mathematical acceptation, has reference to the state of our knowledge of the circumstances under which an event may happen or fail. With the degree of information which we possess concerning the circumstances of an event, the reason we have to think that it will occur, or, to use a single term, our expectation of it, will vary. Probability is expectation founded upon partial knowledge. A perfect acquaintance with all the circumstances affecting the occurrence of an event would change expectation into certainty, and leave neither room nor demand for a theory of probabilities.

A likely impossibility is always preferable to an unconvincing possibility. The story should never be made up of improbable incidents; there should be nothing of the sort in it.

Among all the occurrences possible in the universe the a priori probability of any particular one of them verges upon zero. Yet the universe exists; particular events must take place in it, the probability of which (before the event) was infinitesimal. At the present time we have no legitimate grounds for either asserting or denying that life got off to but a single start on earth, and that, as a consequence, before it appeared its chances of occurring were next to nil. ... Destiny is written concurrently with the event, not prior to it... The universe was not pregnant with life nor the biosphere with man. Our number came up in the Monte Carlo game. Is it surprising that, like the person who has just made a million at the casino, we should feel strange and a little unreal?

All statistics have outliers.

Another mistaken notion connected with the law of large numbers is the idea that an event is more or less likely to occur because it has or has not happened recently. The idea that the odds of an event with a fixed probability increase or decrease depending on recent occurrences of the event is called the gambler's fallacy. For example, if Kerrich landed, say, 44 heads in the first 100 tosses, the coin would not develop a bias towards the tails in order to catch up! That's what is at the root of such ideas as "her luck has run out" and "He is due." That does not happen. For what it's worth, a good streak doesn't jinx you, and a bad one, unfortunately , does not mean better luck is in store.

Any impossibility turned into a possibility is magic.

A statistical anomaly does not prove wrongdoing. Delma Kinney, a fifty-year-old Atlanta man, won $1 million in an instant lottery in 2008 and then another $1 million in an instant game in 2011. The probability of that happening to the same person is somewhere in the range of 1 in 25 trillion.

As the sun sets, something in me rises! Do you think it could be my soul? I feel it's a big probability!

Accidents happen. That's what everyone says. But in a quantum universe there are no such things as accidents, only possibilities and probabilities folded into existence by perception.

Being nice is state of "Probability", not a state of "possibility".

Between the streams of probability & possibility, lies the timeless, spaceless realm where time gets created!

Dawkins’s advice shows that he didn’t understand probability. . . . Dawkins said that a creature the lives millions of years would have a different feeling for the meaning of the chance of an event than we have. If the alien lives a hundred million years, he could have played very many hands of bridge Then, Dawkins said, it would not be unusual for him to see a ‘perfect’ bridge hand where each player was dealt thirteen cards of the same suit. ‘They will expect to be dealt a perfect bridge hand from time to time, and will scarcely trouble to write home about it when it happens.’ He’s wrong. One can easily calculate the chance of Dawkins’s alien experiencing a perfect bridge hand at least once in his lifetime. The shance of getting such a hand in one deal is 4.47 x [10 to the minus 28th power]. If the alien plays 100 bridge hands every day of his life for 100 million years, he would play about 3.65 x [10 to the 12th power] hands. The chance of his seeing a perfect hand at least once in his life is then 1.63 x [10 to the minus 15th power], or about one chance in a quadrillion. That’s less than Dawkins’’ chance of coming to New York for two weeks and winning the lottery twice in a row. Would he bother to write home about it?

Chickens are true creatures of zen - they live only and absolutely for the moment. Their actions one particular second will not necessarily have any influence or bearing on their actions in the next second, nor are they necessarily influenced by their actions of the prior second. Chicken thoughts arrive in their tiny mad little minds like flashes of a strobe light, each light being an action, each flashing with the brilliance of a not very brilliant thing. Each action utterly random. The complete randomness of chaos. Chickens are notorious escape artists, not due to their ability to devise cunning plans as they huddle together in their coop beneath a bare light bulb, scratching out complex diagrams in the dirt, but simply out of sheet unpredictability. They are the pachinko balls of the animal kingdom, effecting their escapes through the simple device of, say, turning left for no particular reason.

I believe that we do not know anything for certain, but everything probably.

I don't simply create probabilities, I guide them.

If scientific reasoning were limited to the logical processes of arithmetic, we should not get very far in our understanding of the physical world. One might as well attempt to grasp the game of poker entirely by the use of the mathematics of probability.

If skeptic can weakly force E, then he can force E.

If the universe was scientific and just left to itself, then we’d have statistical probabilities to rely on. But once people are involved it sometimes becomes much more problematic because they’re erratic. People do crazy things that don’t make sense.

Do not fear to think even the most not-probable.
