## What is the probability of getting either 2 or 4 from the throw of a dice?

Answer: probability of getting 2 is **1/6**. probability of getting 4 is 1/6.

## What is the probability of getting 1 and 2?

Mathematically, the formula for the probability of an event is Number of outcomes for the eventNumber of total possible outcomes. Probability of 1 and 2 = Probability of (1,2) + Probability of (2,1) = 136+136=**118**.

## What is the probability of rolling a 1 or 4 on a number cube labeled 1 through 6?

Explanation: For each number, there is a **16 probability** of rolling it (so 16 for the 1 and also 16 for the 4).

## How do you find or probability?

Probability OR: Calculations

The formula to calculate the “or” probability of two events A and B is this: **P(A OR B)** **= P(A) + P(B) – P(A AND B)**.

## What are the odds of rolling a 1 or 5 with 3 dice?
