Question 1051904
<font face="Times New Roman" size="+2">


For the denominator of your probability fraction you need the total number of students given as 41.


For the numerator you can either count the number of females plus the number of students who are not female that got a 'C', or you can count the number of students who got a 'C' plus the number of females that did not get a 'C' (same number either way).
