Answer 2

Given:
60% of the students did not earn As on their final project.
7% of students who received As on their final project also received As on their final exam.

2.8% is the Probability that a student chosen at random received an A on both final exam and final project.

100% - 60% = 40% of the students earned As on their final project.
7% of the 40% also received As on their final exam.
40% * 7% = 2.8%
