Expert Solution

Step 1
Binomial Distribution: If we have n trials each having two outcomes, say Success and Failure, trials being independent and the probability of success, say p, remaining constant, then the distribution of the number of success follows binomial.
Let us assume X be a random variable denoting the number of success.
Then , n and p being the parameters of the binomial distribution.
The probability mass function of X is given by,
