a) What is the probability that the card is not a face card?
b) What is the probability that the card is either red or numbered?
c) What is the probability that the card is red and numbered?
a) There are 12 face cards - 4 jacks, 4 queens, and 4 kings
That means there are 40 which are NOT face cards
So, the probability is 40/52 = 10/13
b) probability of red is 1/2, probability of numbered is 36/52 or 9/13
So, total probability is 1/2 + 9/13 - (1/2)(9/13) = 31/26 - 9/26 = 22/26 = 11/13
c) probability of red AND numbered is (1/2)(9/13) = 9/26
