Question: Probability of a Car Crash: Among 400 randomly selected drivers in the 20-24 age bracket. 136 were in a car crash during the last year (based on data from the National Safety Council).

(a) If a driver in that age bracket is randomly selected, what is the approximate probability that he or she will be in a car accident during the next year?

(b) Is it unusual for a driver in that age bracket to be involved in a car crash during a year?

(c) Is the resulting value high enough to be concern to those in the 20-24 age bracket?
