college students follows a normal distribution with mean 2.6, and
standard deviation of 0.5. Students with GPA higher than 3.5 are
considered “exceptional”, 3.0 to 3.5 are considered to be “good”,
2.0 to 3.0 are considered “average”, and below 2.0 are considered
to be “poor”.
(a) For a randomly selected student, what is the probability
that he has a “good” GPA?
