The expected value for the number of independent trials to get the first success, and the variance of a geometrically distributed random variable X is: Similarly, the expected value and variance of the geometrically distributed random variable Y = X - 1 (See definition of distribution ) is: That the expected value is (1 − p)/p can be shown in the following way. Let Y be as above. Then WebAfter calculating the probability of the numerator and the probability of the denominator, one can arrive to the same expression.
