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.

Occasionally I glanced at the big blue cradle of civilization hanging in the sky, remembered for the fiftieth or sixtieth or one hundredth time that none of this had any right to be happening, and reminded myself for the fiftieth or sixtieth or one hundredth time that the only sane response was to continue carrying the tune.
Further, the same Arguments which explode the Notion of Luck, may, on the other side, be useful in some Cases to establish a due comparison between Chance and Design: We may imagine Chance and Design to be, as it were, in Competition with each other, for the production of some sorts of Events, and many calculate what Probability there is, that those Events should be rather be owing to the one than to the other.
It is highly probable that we choose our posture, not our problems.
Natural selection is not only a parsimonious, plausible and elegant solution; it is the only workable alternative to chance that has ever been suggested. Intelligent design suffers from exactly the same objection as chance. It is simply not a plausible solution to the riddle of statistical improbability. And the higher the improbability, the more implausible intelligent design becomes. Seen clearly, intelligent design will turn out to be a redoubling of the problem. Once again, this is because the designer himself (/herself/itself) immediately raises the bigger problem of his own origin. Any entity capable of intelligently designing something as improbable as a Dutchman's Pipe (or a universe) would have to be even more improbable than a Dutchman's Pipe. Far from terminating the vicious regress, God aggravates it with a vengeance.
Extremely unlikely events occur every moment and it is not a priori unthinkable that the evolution of life should be due to mere chance than that a particular order in a pack of cards should result from mechanical shuffling.
The Coin of Life example: Say you have a coin with heads on one side and tails on the other side. One side would mean good and the other bad, based on your interpretation or bet of which side of the coin represents a win for you. However, you can't decide the outcome and the coin flips many times throughout your life. Finding balance is flipping the coin in such a way that neither of the sides is of greater importance to you, but if the coin lands on the middle bit, you realize that the space between what you consider good or bad is so small and the probability of landing there is also incredibly small without continuous practice. However, no matter the outcome, you choose to accept the coin as it is, with both sides, and appreciate the importance of both in your life. For the coin of life has meaning and value no matter what side it lands on. It's each individual's choice whether to bet on the outcome or not, but ultimately your coin of life will be spent somehow.
One of the recent arguments from design, that based on the so-called fine-tuning life of some fundamental physical constants, founders on the following objections: an extremely small prior probability merited by the God of theism in light _ if that is the right word _ of the Problem of Evil; the fact that it is not unreasonable to place a substantial probability on the hypothesis that a future theory will fix those values; and the sheer incoherence of computations of the __hances_ of fine-tuning were there no fine-tuner.
Ignorance gives one a large range of probabilities.
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.
