Question

What is the probability of not picking a king if you choose randomly from a pack of 52 cards?

Options

• `1/13`

• `12/13`

• `51/52`

• `1/52`

Answer 1

`12/13`

Explanation:

Since there are 4 kings in a deck of 52, the probability of drawing a king is `4/52 = 1/13`.

Hence, the probability of not picking a king is `1 - 1/13 = 12/13`.

(∵ For an event E, P (E) =1-P (not E)).
