Web2 on independent and identical Bernoulli trials. For each trial, the outcome Y can take on values of 0 or 1, specified by probabilities P(Y=1) = π of success and P(Y=0) = 1- π of failure (where 0 ≤ π ≤ 1). A Bernoulli random variable has a mean of E(Y) = π. For n independent and identical Bernoulli trials, the number of successes follows a binomial … Web15.1 Binomial Distribution. Suppose I flipped a coin \(n=3\) times and wanted to compute the probability of getting heads exactly \(X=2\) times. This can be done with a tree diagram.
