Question

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

Answer 1

Probability(ace or a king) = (
`(2)/(13)`

Explanation:

The probability of drawing an ace from the 52 cards is
`(4)/(52)`

The probability of drawing a king from the 52 cards is
`(4)/(52)`

When you see the word 'or' in probability; you add the two outcomes.

I.e the probability of drawing an ace or a king from a deck of cards =
`(4)/(52)` +
`(4)/(52)` =
`(8)/(52)` =
`(2)/(13)`
