Final answer:
The probability that a penalty in soccer is a PK and the player makes the PK is 0.315.
Step-by-step explanation:
The probability that a penalty in soccer is a PK and the player makes the PK can be found by multiplying the probabilities of the two events. If the average number of penalties that are PKs is 0.45 and the average chance of scoring a PK is 0.70, then the probability can be calculated as follows:
P(PK and make PK) = P(PK) * P(make PK)
= 0.45 * 0.70
= 0.315
