How to find the probability for this event?
Wednesday, February 25th, 2009
A ferry carries 25 passengers. The weight of each passenger has a normal distribution with mean 168 lbs and variance 361 lb squared. Safety regulations state that, for this particular ferry, the total weight of passengers on the boat should not exceed 4250 lbs more than 5 percent of the time. What is the probability that the total weight of passengers on the ferry will exceed 4250 lbs?
