If one student is chosen at random,
a. Find the probability that the student was female: 
P = 55/79

b. Find the probability that the student was female AND got a "B": 
P =(20/79)

c. Find the probability that the student was female OR got a "B": 
P = 55/79 + 23/79 -  20/79 = 58/79 

d. If one student is chosen at random, find the probability 
that the student got an 'B' GIVEN they are female: 
P = {{{(20/79)/(55/79)}}} = 20/55

Wish You the Best in your Studies.
