When you roll a single die, you can get six possible outcomes: 1, 2, 3, 4, 5, or 6. However, when you roll two dice, this number jumps to 36, as shown in the following figure.

## What is the formula for calculating probability?

**How to calculate probability**

- Determine a single event with a single outcome.
- Identify the total number of outcomes that can occur.
- Divide the number of events by the number of possible outcomes.

## What is the probability of rolling a 2 or 4?

There is a **33.33% chance** of getting a 2 or 4.

## What is the probability of rolling a 2 or rolling a 5?

Explanation: There is a **16 probability** of getting a 2 on the first roll and a 16 probability of getting a 5 on the second roll.

## What is the probability of getting a multiple of 2 in rolling a die?

So, probability of rolling a multiple of 2 with one toss of a number cube is **1/3**.
