Hi,

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

                A	  B	  C	  Total
Male	16	2	13	31
Female	12	11	14	37
Total	28	13	27	68


If one student is chosen at random,

Find the probability that the student was female: = 28/68
Correct  

Find the probability that the student was male AND got a "B": = 2/68
Correct  

Find the probability that the student was male OR got an "B": = 31/68 + 27/68
Correct  

If one student is chosen at random, find the probability that the student got a 'B' GIVEN they are male = 2/31

Wish You the Best in your Studies.
