Find the probability of drawing either an ace or a king from a pack of card in a single draw.

Text Solution

Verified by Experts

The correct Answer is:
`(2)/(13)`
There are 52 cards in the pack and each card has equal probability of getting drawn that is `(1)/(52)`
There are four king and four ace cards.
So, probability of drawing either an ace or a king
`= (1)/(52) + (1)/(52) + ... + (1)/(52)` (8 times)
`= (8)/(52) = (2)/(13)`
