Question

The grade distribution for students in the introductory

Answer 1

Using the given discrete probability distribution, it is found that the probability that a randomly selected student has a grade higher than a C is given by:

P(X > 2).

What is the discrete probability distribution for the grade?

From the table, it is given by:

• P(X = F) = P(X = 0) = 0.04.

• P(X = D) = P(X = 1) = 0.05.

• P(X = C) = P(X = 2) = 0.17.

• P(X = B) = P(X = 3) = 0.31.

• P(X  = A) = P(X = 4) = 0.43.

Grades A and B are greater than C, hence the probability of getting a grade higher than C is given by:

P(X > C) = P(X = A) + P(X = B) = P(X = 3) + P(X = 4) = P(X > 2).
