Answer:
a) The probability of drawing a king of hearts is 1/52, because there is only 1 king of hearts out of 52 cards.
b) The probability of drawing a diamond is 13/52, since there are 13 diamonds in a standard deck of 52 cards.
c) The probability of drawing a jack or queen is 8/52, since there are 4 jacks and 4 queens in a standard deck of 52 cards.
d) The probability of drawing a black card is 26/52, since there are 26 black cards (clubs and spades) in a standard deck of 52 cards.
e) Because there are 4 aces and 13 spades in a regular 52-card deck, the chance of drawing an ace or a spade is 17/52, but we must deduct the probability of drawing the ace of spades (which is already treated as a spade) to avoid double-counting
4/52 + 13/52 - 1/52 = 16/52 = 4/13.
