Binomial random variables in r

WebThe binomial random variable is defined as the sum of repeated Bernoulli trials, so it represents the count of the number of successes (outcome=1) in a sample of these trials. The argument size in the binom functions tells R … WebIn probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean -valued outcome: success (with probability p) or failure (with probability ).
