Cars arrive randomly at an intersection at an average rate of 100 cars per hour. The likelihood, or probability, that at least one car will enter the intersection within a 5): period ofx minutes can be estimated by P(x}=1 e 3 _ a. Find the likelihood that at least one car enters the intersection during a 5minute period. b. Graphically determine the value of x that gives a 5050 chance of at least one car entering the intersection during an interval olx minutes. a. The likelihood that at least one car enters the intersection is about '36. (Round to the nearest integer as needed.)
