Elevator ride: Engineers are designing a large elevator that will accommodate 44 people. The maximum welght the elevator can hold safely is 8228 pounds. According to the National Health Statistics Reports, the welghts of adult U.S. men have mean 186 pounds and standard devlation 60 pounds, and the weights of adult U.S. women have mean 157 pounds and standard devlation 69 pounds.

Part 2 of 3 (b) If a random sample of 44 adult men ride the elevator, what is the probability that the maximum safe weight will be exceeded? Round the answer to at least four decimal places. The probability that the maximum safe weight will be exceeded is
