60% of the students in mr. macgregor’s class did not earn a as on their final projects. 7% of the students who received as on their final projects also received as on their final exams. find the probability that a student chosen at random received an a on both the final exam and the final project.

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%

A. 7/250The other answer is correct, but needs to be put into fraction form to be answered correctly.

Hope I helped! I don't take credit for my answer, just wanted to make the other answer better!
