Let r be a binomial random variable representing the number of successes out of n trials.

(a) Explain why the sample space for r consists of the set {0, 1, 2, ..., n} and why the sum of the probabilities of all the entries in the entire sample space must be 1.

Out of n trials, there can be 0 through n - 1 successes. The sum of of the probabilities for all elements of the sample space is usually 1.

Out of n trials, there can be 0 through n - 1 successes. The sum of of the probabilities for all elements of the sample space must be 1.
