# For an experiment in which a single die is rolled, the sample space may be {1, 1, 2, 3, 4, 5}. What is the probability of getting a 1?

Probability is the measure of the possibility of occurrence of an event. It has many applications in fields other than mathematics too.

## Answer: For an event of rolling a die with sample space {1, 1, 2, 3, 4, 5}, the probability of getting 1 is 1/3.

Let's understand the solution in detail.

**Explanation:**

We know that,

Probability of an event = Number of favourable outcomes / total sample space

The sample space of the given event: {1, 1, 2, 3, 4, 5}.

Number of favourable outcomes = 2 = {1, 1}.

Hence, the probability of getting 1 = favourable outcomes / total sample space = 2/6 = 1/3.
