Hi,

Note: The probability of x successes in n trials is: 

P = nCx*  where p and q are the probabilities of success and failure respectively. 

In this case p(defective) = 3/8 = 3.75   & q = 5/8 = 6.25

nCx = 

(a)n= 1 P(no defective) = (5/8)^1 = 5/8

(b)n= 2 P(no defective) = (5/8)^2

(c)n= 3 P(no defective) = (5/8)^3

(d)n= 5  P(no defective) = (5/8)^5

Calculator will make short work of completing the work
