Question

Options

• `1/13`

• `9/13`

• `4/13`

• `12/13`

Answer 1

A card is drawn at random from a well-shuffled pack of 52 cards. The probability that the card drawn is not an ace is `underlinebb(12/13)`.

Explanation:

Total number of cards = 52

Number of ace cards = 4

Probability of the card which is not an ace = 1 – P(ace card)

= `1 - 4/52`

= `1 - 1/13`

= `(13 - 1)/13`

= `12/13`
