Problema Solution
a card game is drawn at a random from a standard deck of cards. what is the probability that the card is less than 7 given that the card is not 2
Answer provided by our tutors
p(not 2) = 48/52
p(<7) = 24/52
p(of 7/not 2) = p((not 2) U (< 7))/p(not 2)
= (20/52)/(24/52)
=20/24 = 0.8333
