              X has a normal distribution with a mean of 80.0 and a standard deviation of 3.5. Find the
              following probabilities:

              (A) P(x < 77.0)
              (B) P(76.0 < x < 82.0)
              (C) P(x>87.0)

              Solution:

              The information in the given problem can be represented with the following notations:

              Population mean = µ = 80
