Question

An experiment consists of identical trials. Each trial can result in one of two possible outcomes: success or failure. The trials are independent. The probability of success is constant from trial to trial. Let X be a random variable that counts the number of trials necessary to obtain the first success. Show that E(X) = 1/p (without using calculus!)
