WebDec 31, 2024 · For example, suppose you flip a coin 10 times, and you want to know the probability of getting exactly 5 heads. In this case, X is a binomial random variable that counts the number of heads in the 10 flips. The probability of success is p = 0.5 (since the coin is fair), and the probability of failure is 1 - p = 0.5.
