In a sales effectiveness seminar, a group of sales representatives tried a few approaches to selling a new automobile to a customer: the aggressive approach, the passive approach and a mixture of both. For 1740 customers, the following record was kept:

Sale No Sale Total
Aggressive 265 315 580
Passive 481 99 580
Column 746 414 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 (a) Compute P(S), P(S I A), and P(S | Pa). (Enter your answers as fractions.)
