Question

Suppose we have assigned grades for the 11 students in our data:

Grade A for Students who scored ≥ 90; B for students who scored ≥ 80 and < 90; C for students who scored ≥ 70 and < 80; D for students who scored ≥ 60 and < 70; F for students that scored < 60.

Following the grade scheme, 7 students received an A; 1 student received a B; 0 students received a C; 0 students received a D; 1 student received an F.

Question 2:

a) What is the probability that a student received grade A and grade B?

b) What is the probability that a student received grade A? (i.e. P(A) is..)

c) What is the probability that a student received grade B? (i.e. P(B) is...)

d) What is the probability that a student received grade C? (i.e. P(C) is..)

e) What is the probability that a student received grade D? (i.e. P(D) is..)
