Solution

as I can see in the image you just need the last question

the probability that the 2 callers complain and the third does not is about

well this is a binomial distribution with

p = 0.53

q= 1 - 0.53 = 0.47

n = 3

and we need to find P(x=2)

P(X = x) = nCx* p^x * q^(n-x)

P(x=2) = 3C2 * 0.53 ^2 * 0.47 ^( 3-2 ) = 0.396

the probability that the 2 callers complain and the third does not is about 0.396
