A card is drawn from a standard deck of 52 playing cards. What is the probability that the card is an ace or a king?

1 Answer

Answer:

#2/13#

Explanation:

There are 52 cards in a standard deck: 13 ordinal cards (Ace - 10, Jack, Queen, King) and 4 of them - one to each suit (hearts, diamonds, clubs, spades) and so we have #4xx13=52#.

There are 8 cards that fit the question (4 each of aces and kings).

And so in a random draw, the odds of drawing one of those 8 cards out of the total number of 52 is:

#8/52#

which we can simplify:

#8/52=2/13#
