What is the probability that the student is a freshman given he doesn’t carry a credit card?
Class Credit Card Carrier Not a Credit Card Carrier Total
Freshman 33 27 60
Sophomore 6 24 40
Total 39 61 100
==========
Ans: P(F | C')
= P(F AND C')/ P(C')
= (27/100)/(61/100)
= 27/61
================
Notice that, when you have a conditional like this (C'), that
conditional becomes your Universe.
