Answer 2

Given:

A fair die is rolled

To find:

The probability of getting a prime number

Solution:

The probability of getting a prime number is 1/2.

We can find the probability by following the given steps-

We know that the probability of an event is calculated by dividing the number of favorable outcomes and the total number of outcomes.

Probability=Number of favorable outcomes/ Total number of outcomes

We know that a fair die is rolled.

We can obtain 1, 2, 3, 4, 5, or 6.

So, the total number of outcomes on rolling a die is 6.

Now to obtain a prime number, the die should show 2, 3, or 5.

So, the number of favorable outcomes is 3.

We will put the values in the formula to get the probability.

The probability of getting a prime number=3/6

=1/2

Therefore, the probability of getting a prime number is 1/2.
