Asummer resort rents rowboats to customers but does not allow more than four people to a boat. each boat is designed to hold no more than 800 pounds. suppose the distribution of adult males who rent boats, including their clothes and gear, is normal with a mean of 190 pounds and standard deviation of 10 pounds. if the weights of individual passengers are independent, what is the probability that a group of four adult male passengers will exceed the acceptable weight limit of 800 pounds?
