A college professor teaching a class of Psychology gives the following grades during Fall semester: 15% A’s, 20% B’s, 40% C’s, and 10% D’s. The remainder of the students receive an F. What is the probability that a randomly selected student does not earn an A in this class?

85%

Step-by-step explanation:

Because we can see that only 15% of the class obtained A's, and the question only refers to those that did not receive A's, we can subtract the 15% of the 100% whole to get 85%. This can also be written as 85/100 or 17/20(simplified).
