You can put this solution on YOUR website!
you can make a box to show the scores.
the box would look like this: 


gender       A           B          C            TOTAL

male         17          5          2            24

female       7           11         12           30

total        24          16         14           54


if one student was chosen at random, find the probability that the student was female.

the total number of females is 30.
the total number of students is 54.

the probability that the student is female would be 30/54 = 10/18 = 5/9.

they did not specify that the student was female and got a certain grade.

they only specified that the student was female regardless of what grade she received.

what you got was the probability that a randomly chosen student was female and got an A.
