## What is the probability of getting a sum of a pair of dice?

There are six faces for each of two dice, giving 36 possible outcomes. If the two dice are fair, each of 36 outcomes is equally likely. Three outcomes sum to 4: (1+3), (2+2) and (3+1). Probability of getting a sum of 4 on one toss of two dice is 3/36, or **1/12**.

## What is the probability of getting a sum of 6?

Probability of getting a total of 6 = **5/36**.

## How do you find the sum of probabilities?

The probability that A or B will occur is the sum of the probability of each event, minus the probability of the overlap. **P(A or B)** **= P(A) + P(B) – P(A and B)**

## What is the probability that the sum of the two dice is 7?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is **6/36 = 1/6**.
