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:

	Sale	No Sale	Row Total
Aggressive	261	319	580
Passive	489	91	580
Column Total	750	410	1160

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.

(c) Compute P(A and S) and P(Pa and S). (Enter your answers as fractions.)

P(A and S) =

P(Pa and S) =

(f) Compute P(A or S). (Enter your answer as a fraction.)
P(A or S) =
