# A Die is Thrown Once. Find the Probability of Getting a Number Other than 3. - Mathematics

Short Note

A die is thrown once. Find the probability of getting a number other than 3.

#### Solution

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 = 5
∴ Probability of getting a number other than 3 =  P (E) = "Number of favourable outcomes"/"Total number of possible outcomes" = 5/6
