Question

A card is randomly drawn from an ordinary deck of playing cards. What is the probability that the card is a king or a diamond?

Answer 1

There are 52 possible outcomes when you draw one card from a standard deck. Hence, 52 is the denominator of your probability fraction.

Answer 2

33%

Explanation:

An ordinary deck of cards has 52 cards in total.

There are 4 kings in an ordinary deck of cards. So the possibility of drawing a king is 4/52.

There are 13 diamond cards in an ordinary deck of cards. So your chances of drawing a diamond are 13/52.

Now 'OR' = add and 'AND' = multiply.

So 4/52 + 13/52 = 17/52.

17/52 = .326 --> Round up = .33 --> Change to percentage: 33%.
