Assume that fifteen student drivers are registered for a driver education course.a) What is the probability that more than 4 but less than 10 are registered on a pass/fail basis?b) What is the probability that exactly seven are registered on a pass/fail basis?c) Determine the variance for the students who have registered on a pass/fail basis?d) Based on part c), find V(7X - 49).e) The manager of the driving school just found out that there are actually eleven student drivers who are registered for a driver education course instead of fifteen. What is the probability that exactly six are registered on a pass/fail basis?
