In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept: Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa = passive approach, S = sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on.

Question

In a sales effectiveness seminar, a group of sales representatives tried two approaches to selling a customer a new automobile: the aggressive approach and the passive approach. For 1160 customers, the following record was kept:

Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for events: A = aggressive approach, Pa = passive approach, S = sale, N = no sale. So, P(A) is the probability that an aggressive approach was used, and so on.

(a) Compute P(S), P(S | A), and P(S | Pa). (Enter your answers as fractions.) Simplify the fraction if needed

P(S) = ?

P(S | A) = ?

P(S | Pa) = 95/116

(b) Compute P(A and S) and P(Pa and S). (Enter your answers as fractions.) Simplify the fraction if needed

P(A and S) = ?

P(Pa and S) = 95/232

(c) Compute P(N) and P(N | A). (Enter your answers as fractions.)  Simplify the fraction if needed
