Question

what is the probability of drawing a king of hearts from a deck of 52 cards

Answer 1

There is only 1 king of hearts in a deck, so there is a 1/52 probability.

Answer 2

oops right :):)

Answer 3

You didn't say if the deck contained a wild card. Or if someone dropped the deck the same time someone dropped their deck and the two decks mixed therefor adding more than 52 cards to the deck.
