Asked by Amanda

Giving a test to a group of students, the grades and gender are summarized below

A B C Total
Male 18 16 8 42
Female 7 17 9 33
Total 25 33 17 75


If one student is chosen at random,

Find the probability that the student was NOT a female that got a "A"
Answered by Damon
Just like the other one
there are 7 females with A out of 75 students
probability that student is female with A = 7/75
so
probability not female with A = 1-7/75
= 0.907
