A particular professor never dismisses class early. Let x denote the amount of additional time (in minutes) that elapses before the professor dismisses class. Suppose that x has a uniform distribution on the interval from 0 to 10 minutes. The density curve is shown in the following figure:
a. What is the probability that at most 5minutes elapse before dismissal?
b. What is the probability that between 3 and 5minutes elapse before dismissal? |
