An elevator has a placard stating that the maximum capacity is 1872 lb—12 passengers.​ So, 12 adult male

passengers can have a mean weight of up to 1872 divided by 12 equals 156 pounds.

1872/12=156 pounds. If the elevator is loaded with 12 adult male​ passengers, find the probability that it is overloaded because they have a mean weight greater than 156 lb.​ (Assume that weights of males are normally distributed with a mean of 161 lb and a standard deviation of 35 lb​.) Does this elevator appear to be​ safe?

The probability the elevator is overloaded is nothing


​(Round to four decimal places as​ needed.)
