PLEASE HELP ME ITD MEAN ALOT Find the slope

At school there are 526 students and 263 are girls about how likely is it that a randomly chosen student will be a boy

Suppose that an airline uses a seat width of 16.516.5 in. assume men have hip breadths that are normally distributed with a mean of 14.414.4 in. and a standard deviation of 0.90.9 in. complete parts (a) through (c) below. (a) find the probability that if an individual man is randomly selected, his hip breadth will be greater than 16.516.5 in. the probability is nothing. (round to four decimal places as needed.)
