A medium sized company has 15 employees who hold managerial positions. Of them, 4 are minorities and 11 are not. The company wants to select 3 employees to negotiate a new contract. If 3 employees are selected at random from this group of 15, find the probability that: a) Exactly 2 are minorities. (show all work and round final answer to 3 decimal places) First, write the values N, r, N-r, n, n-x then use them to set up the problem N= r= , N-r = n= , n-x= P(exactly 2 minorities) =
