Question 418573
 Alice and Bob each have a deck of playing cards. Each flips over a randomly selected card.
Assume that all pairs of cards are equally likely to be drawn. Determine the following
probabilities:
(a) The probability that at least one card is an ace.
P(no ace) = 48/52
P(at least one ace) = 1 - (48/52)^2 = 0.1479
-----------------------------------------------
(b) The probability that the two cards are of the same suit.
(1/4)^2
----
(c) The probability that neither card is an ace.
(48/52)^2
------
(d) The probability that neither card is a diamond or club.
(26/52)^2
