For more math shorts go to w. Expected Value of a Binomial Distribution Arthur White 14th November 2016 Recall that we say a random variable X Binomnˇ follows a binomial distribution if nindependent trials occur with a constant probability of success PSuccess ˇand X corresponds to the total number of observed successes. P X k n C k p k q n k.
X can only take values 0 1 2 n but the expected value mean of X may be some value other than those that can be assumed by X.
The expected value or mean of a binomial distribution is calculated by multiplying the number of trials n by the probability of successes p or n x p.
