Let X be a random variable that follows the normal with mean of 80 and variance 49. a) What is P(X<87)? b) What is P(72<X<95)? c) What is P(X>73)? d) Find x such that P(75<X<x)=0.65 . e) What is P(X?73) ?

Given:X is a random variable that follows a normal distribution with mean ? = 80 and variance ?^2 = 49.a) To find P(X < 87), we need to standardize th
