Question

The instructor of a discrete mathematics class gave two tests. Forty percent of the students received an A on the first test and 8% of the students received A's on both tests. What percent of the students who received A's on the first test also received A's on the second test?

Answer 1

The percent of students who received A's on both tests is 32%.

Step-by-step explanation:

To find the percent of students who received A's on both tests, we can subtract the percent of students who received A's on only the first test from the total percent who received A's on the first test.

Since 8% of students received A's on both tests and 40% received A's on the first test, the percent of students who received A's on the first test and also on the second test is 40% - 8% = 32%.

Therefore, 32% of the students who received A's on the first test also received A's on the second t
