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

A B C Total
Male 8 10 12 30
Female 4 11 3 18
Total 12 21 15 48

If one student was chosen at random,

find the probability that the student got an A.

(total who got A)/(total students)

To find the probability that a student chosen at random got an A, we need to determine the total number of students who got an A and divide it by the total number of students in the group.

Looking at the summarized data, we can see that a total of 12 students in the group got an A. The total number of students in the group is 48.

Therefore, the probability that a student chosen at random got an A is:

P(A) = Number of students who got an A / Total number of students
= 12 / 48
= 1/4
= 0.25

So, the probability that a student chosen at random got an A is 0.25 or 25%.
