Brad is testing whether school is more enjoyable when students are making high grades. He asked 110 students if they enjoyed school and whether their GPA was above or below 3.5. He found that 38 of the 45 students with a GPA above 3.5 reported that they enjoyed school, and 7 of the 65 students with a GPA below 3.5 reported that they enjoyed school. What is the probability that a student with a GPA below 3.5 does not enjoy school?

i think from the information above, we know that

a total of 65 do not enjoy school, 58 earn gpas less than 3.6

Therefore, i think the probability would be :
58/65 or around 89 %

Hope this helps
