A test was given to a group of students. The grades and gender are summarized below

enter image description here

If one student is chosen at random from those who took the test,

Find the probability that the student got a 'C' GIVEN they are female.

The total females is 43, total C's are 19
The total females who have a C is 5 of 19
So my answer is 5/19, is this wrong?

  • $\begingroup$ You've figured out the probability that the student is female, given that they got a C (you've taken the number of female C's and divided by the total number of C's). $\endgroup$ – Arthur Apr 29 '15 at 19:51

AHHH, I was reading it wrong.
The answer is 5/43.

I was reading, the probability that a student is female given they got a C.
which is 5/19
