Anne 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: (1)
The probability that at least one card is an ace, (2) the probability that the two cards are of the
same suit, (3) the probability that neither card is an ace, and (4) the probability that neither card
is a diamond or club.
