c) The difference of mean and variance of a binomial distribution of 9 trails is 4. Find the probability p of success of the binomial distribution. Also find the probability of (i) exactly two successes and (ii) less than 2 successes.

To solve this problem, we'll use the properties of a binomial distribution. 

Given that the mean and variance difference is 4, we have:

Mean (μ) - Variance (σ^2) = 4

For a binomial distribution with n trials, mean (μ) = np and variance ______ __________ _____ _________ ________ ________ _______ ____.
