12. Mimi just started her tennis class three weeks ago. On average, she is able to return 20% of her opponent's serves. Assume her opponent serves 8 times. (a) Let X be the number of returns that Mimi gets. As we know, the distribution of X is a binomial probability distribution. What is the number of trials (n), probability of successes (p) and probability of failures (q), respectively? (b) Find the probability that she returns at least 1 of the 8 serves from her opponent. (Round the answer to 3 decimal places) Show all work. Just the answer, without supporting work, will receive no credit
