Transcribed Image Text: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 | 252 | 328 | 580 |
| Passive | 475 | 105 | 580 |
| Column Total| 727 | 433 | 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.
(Note: It is presumed that probabilities are calculated as fractions.)
