Question

Bryce is testing whether school is more enjoyable when students are making high grades. He asked 100 students if they enjoyed school and whether their GPA was above or below 3.0. He found that 33 of the 40 students with a GPA above 3.0 reported that they enjoyed school, and 5 of the 60 students with a GPA below 3.0 reported that they enjoyed school. What is the probability that a student with a GPA below 3.0 does not enjoy school?

85%
92%
65%
75%

Answer 1

The answer is 92%.

Explanation:

5 of the 60 students reported that they like school. This means that the other 55 don't like school. You then divide 55/60 and you get 92%. So, therefore, your answer is 52%.

Answer 2

Since 5 people do, you can do 60-5 which is 55. You then solve this equation:

55/60 which is 0.916666666666
This is rounded to 92%! :)
