Mean and Standard Deviation of a Proportion To find the proportion of times something occurs, we divide the count (often a binomial random variable) by the number of trials n. Using the formula for the mean and standard deviation of a binomial random variable, derive the mean and standard deviation of a proportion resulting from trials and probability of success p.
