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.)

Q7 (b) some electronic devices are better used than new: The failure rate is higher when they are new than when they are six months old. For example 53.20% of the personal music players of a particular brand have a flaw. If the player has the flaw, it dies in the first six months. If it does not have this flaw, then only 6.800% fail in the first six months. Yours died after you had it for three months. What are the chances that it has this flaw?
