Problem 3 A discrete probability distribution arising in a large number of physical models is the binomial distribution. A discrete random variable X has a binomial distribution when its PMF is defined as (see Table 1 at the end of the Reader) Px (x) = up* (1 -p)", x= 0, 1, 2, .. ., n where n and p are the two parameters of the distribution, n being a positive integer, and 0 6], and P[4
