Question

From a set of 17 cards, numbered 1, 2, …. 17, one card is drawn. What is the probability that the number is a multiple of 3 or 7?

Options

• `5/17`

• `7/17`

• `8/17`

• `6/17`

Answer 1

`7/17`

Explanation:

The total number of possible outcomes is 17

The number of favourable outcomes is 3, 6, 7, 9, 12, 14 and 15 = 7

Thus, the required probability = `" number of favorable outcomes"/"total number of outcomes"`

`= 7/17`.
