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?

We can forget the first part of the problem all we need to know is below 3.5 gpa witch has 65 students and 7 said they like school we need who doesnt like it witch is 58 students because 10% of 65 is 6.5 we know its just a tad higher so 11% of 65 is 7.15 its a little lower than 11% that we have to subtract its about 10.8% dislike so subtract from 100% and you get 89.2 your answer should be

89
