The probability of a certain event can be regarded as a function of p. In the ideal case we take the prior probability that the coin is biased to be exactly zero. Item Selection With Biased-Coin . Up to this point, regions of possibility are cut into increments of 1/16 pieces. It comes up heads with probability 3/4, while coin 2 will flip heads with probability 1/2. For a deeper dive into this topic, see these notes by Michael Mitzenmacher from Harvard University. simulated conditions. For the simulation code, the function call random(1, 6) returns a random number in between the two numbers (inclusive), so the result of random(1, 6) is like rolling a 6-sided die, and random(1, 2) is like flipping a coin. On each flip, P[H] =p. For the coin flip example, N = 2 and π = 0. But before I do that, I’m going to introduce the concept of probability distributions which is going to be helpful along the way.
