27. Let x represent the amount of time it takes a student to park in the library parking lot at the university. Suppose we know that the distribution of parking times can be modelled using an exponential distribution with a mean of 4 minutes. Find the probability that it will take a randomly selected student more than 10 minutes to park in the library lot. a) .670320 meanz 4.0 X z lo b) .917915 P(X>10) = e
