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 | 255 | 325 | 580 |
| Passive | 500 | 80 | 580 |
| Column Total | 755 | 405 | 1160 |
Suppose a customer is selected at random from the 1160 participating customers. Let us use the following notation for
(a) Compute P(S), P(S | A), and P(S | Pa). (Enter your answers as fractions.)
P(S) =
P(S | A) =
P(S | Pa) =
(b) Compute P(A and S) and P(Pa and S). (Enter your answers as fractions.)
P(A and S)=
P(Pa and S) =
(c) Compute P(N) and P(N | A). (Enter your answers as fractions.)
P(N) =
P(N | A) =
