Question

For a standard deck of 52 what is the probability of randomly picking either an ace or a king?

Answer 1

`2/13~=15.4%`

Explanation:

There are 13 ordinal cards (Ace - 10, Jack, Queen, King) in each of 4 suits (Spade, Club, Diamond, Heart) and so there are 52 cards in a standard deck (`4xx13=52`).

If we pick a random card, what is the probability of picking either an Ace or King?

Probability measures the percentage or fraction of the time we'll achieve a certain result (in a fraction, this is the numerator) over the total number of possible outcomes (this is the denominator). In this question, there are 8 cards that will satisfy our conditions (4 Kings, 4 Aces) and 52 total outcomes, so we get:

`8/52=4/26=2/13~=15.4%`
