When crossing the Golden Gate Bridge, traveling into San Francisco, all drivers must pay a toll. Suppose the amount of time (in
minutes) drivers wait in line to pay the toll follows an exponential distribution with a probability density function of f(x)
0.11.-0.11%
-
a. What is the mean waiting time that drivers face when entering San Francisco via the Golden Gate Bridge? (Round your answer to 2
decimal places.)
Mean waiting time
b. What is the probability that a driver spends more than the average time to pay the toll? (Round intermediate calculations to at least
4 decimal places and final answer to 4 decimal places.)
Probability
c. What is the probability that a driver spends more than 18 minutes to pay the toll? (Round intermediate calculations to at least 4
decimal places and final answer to 4 decimal places.)
