Question 1051904: Giving a test to a group of students, the grades and genders are summarized below.

A B C Total Male 8 5 6 19 Female 15 3 4 22 Total 23 8 10 41

If one student is chosen at random,
find the probability that the student was female OR received a grade of "C". (Leave answer to four decimal places.)

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).
