WebCalculation of expected value for binomial random variables. It is the multiplication of the number of trials and probability of success event. Example: A coin is tossed 5 times and the probability of getting a tail in each trial is 0.5. So, Number of trials (X) = 5, and Probability of success event = 0.5. Expected value = X*P (X) = 5 * 0.5 = 2.5.
