Question

Cards, each marked with one of the numbers 6, 7, 8, ..., 15, are placed in a box and mixed thoroughly. One card is drawn at random from the box. What is the probability of getting a card with a number less than 10?

Options

• `3/5`

• `1/3`

• `1/2`

• `2/5`

Answer 1

`bb(2/5)`

Explanation:

All possible outcomes are 6, 7, 8................15.

Number of all possible outcomes = 10

Out of these, the numbers that are less than 10 are 6, 7, 8 and 9.

Number of favourable outcomes = 4

∴ P(getting a number that is less than 10) = `4/10 = 2/5`
