# What is the probability of rolling a sum of 5 if two regular 6-sided number cubes are rolled?

**Solution:**

Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.

Probability = Number of favorable outcomes/ Total number of outcomes----1

We know that

Favorable outcomes = (1, 4), (2, 3), (3, 2), (4, 1)

The total number of outcomes = 36

Substituting the values in equation 1.

Probability = 4/36

Probability = 1/9

Therefore, the probability is 1/9.

## What is the probability of rolling a sum of 5 if two regular 6-sided number cubes are rolled?

**Summary:**

The probability of rolling a sum of 5 if two regular 6-sided number cubes are rolled is 1/9.
