(a)
There are 13 diamonds in a deck of cards, out of 52 cards total. So, the probability that the card you draw is a diamond is
13 / 52 = 1/4 = 0.25
(b)
There are four kings in the deck, so the probability is
4 / 52 = 1/13 = 0.0769...
(c)
There are four aces and four kings in the deck, so there are 8 cards total that we are interested in. The probability of drawing an ace or a king is therefore
8 / 52 = 2/13 = 0.1538...
