Probability, physics, and the coin toss

Exactly how physics and probability come together in the coin-toss problem was analyzed by Joseph Keller, who studied a coin of zero thickness that spins end over end with-out air resistance and lands without bouncing. Keller proved mathematically that the idealized coin becomes fair only in the limit of infinite vertical and angular velocity.

experiment. At this level, quantum probability is like coin-tossing. One cannot say what the outcome will be for a toss of an individual coin. Many tosses are needed to see that the chance of “heads” is 0.50 for an unbiased coin. The idea of “hidden” variables in quantum mechanics can be explained using coin tosses. While we say that ...

Grinstead and Snell’s Introduction to Probability

Let Y be the random variable which represents the toss of a coin. In this case, there are two possible outcomes, which we can label as H and T. Unless we have reason to suspect that the coin comes up one way more often than the other way, it is natural to assign the probability of 1/2 to each of the two outcomes.

A Short Introduction to Probability

Example 1.1 (Coin Tossing) The most fundamental stochastic experiment is the experiment where a coin is tossed a number of times, say ntimes. Indeed, much of probability theory can be based on this simple experiment, as we shall see in subsequent chapters. To better understand how this experiment behaves,

P(k;n;p) = n k p (1 p)n (2) A common example of a binomial process is coin tossing, in which we would assign k=# heads, n=# coin tosses, and p=50% (likelihood of landing heads for a fair coin). For plots of the shapes of this distribution and the Pois-son distribution, refer to Appendix A. I.3.

Introduction to Bayesian Learning

Although tools exist for all of these tasks, the sheer scale of even the most prosaic world can require months or years of labor. An alternative approach is to create these models from existing data, either designed by artists or captured from the world.

This quantity is called the factorial. We’ll see
