Explanation:
Binomial distribution is a frequency distribution of possible number of successful outcomes in given number of trials n, in each of which there is the probability of success is p (and q=1-p is probability of failure)
The mean and standard deviation of a binomial distribution are given by np and npq.
Here n=13,p=524 and q=1524=1924.
Hence mean is 13×524=2.708
Standard deviation is 13×524×1924
=124×1235=4.8696=1.464
