An elevator has a placard stating that the maximum capacity is 2370 Pounds-15 passengers. So, 15 adult male passengers can have a mean weight of up to 2370/15 = 158 pounds. If the elevator is loaded with 15 adult male passengers, find the probability that it is overloaded because they have a mean weight greater than 158 lbs.

The probability the elevator is overloaded is (Round to four decimal places as needed.)
