Quizplus · Accepted Answer

The probability that a student did not receive an A in general chemistry is calculated by subtracting the probability of receiving an A in general chemistry from 1. The probability of receiving an A in general chemistry is 72/540. Therefore, the probability of not receiving an A is 1 - (72/540) = 0.867.
