Answer 1

A die is thrown once. Probability of getting a number other than 3 is `bbunderline(5/6)`.

Explanation:

Let E be the event of getting a number other than 3.

Then, the favourable outcomes are 1, 2, 4, 5 and 6.

Number of favourable outcomes (n(E)) = 5

The total number of possible outcomes is the number on its face: 1, 2, 3, 4, 5, 6.

n(S) = 6

∴ Probability of getting a number other than 3.

P (E) = `"Number of favourable outcomes"/"Total number of possible outcomes"`

= `5/6`
