Only grades possible are A,B,C, or lower than a C. Probability of an A is .40, B is .28, C is .11
probability of an A or B?
Probability of an A,B, or C?
Probability of lower than a C?
A or B: .40+ .28= .68
A, B, or C: .40+ .28+ .11= .79
Lower than C: .40+ .28+ .11= .79
1- .79= .21
With probability, the sum must equal to 1
