Expert Solution

Solution:- Given that n = 18, p = 0.15

a. P(X = 5) = 0.0787

b. P(X <= 4) = 0.8794

Suppose that a class contains 15 boys and 30 girls, and that 10 students are to be selected at random for a special assignment. Find the probability that exactly 3 boys will be selected. I need explanation and calculation, the calculation and explanation should equal atleast 300 words, nothing less and nothing irrelevant please, otherwise i will give thumbs down
