Question

A call centre aims to deal with calls in less than 5 minutes

calls come in randomly

Answer 1

1/8

Explanation:

Let "A" = the next call of a customer's complaint

Let "B" = the next call completed under 5 minutes

P(A) = 1/4

P(B) = 1/2

So ----> P(AB) = P(A) times P(B) P(AB)

= 1/4 times 1/2 = 1/8
