• `1/2`

• `2/3`

• `1/6`

• `5/6`

Answer 1

A die is thrown once. The probability of getting a number which is not a factor of 36, is `bbunderline(1/6)`.

Explanation:

When a die is thrown, the sample space (S) is given by

S = {1, 2, 3, 4, 5, 6}

∴ n(S) = 6

From these, the numbers that appear on the die and are factors of 36 are:

1, 2, 3, 4, 6

The only number on the die that is not a factor of 36 is 5.

Thus, the number of favourable outcomes = 1.

∴ Probability = `("Number of favorable outcomes")/("Total outcomes")`

= `1/6`
