## What are all the possible outcomes of rolling 2 dice?

Note that there are **36 possibilities for (a,b)**. This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.

## What is the probability of getting an even sum of score in a throw of 2 dice?

Thus, we have P(even sum)=**1/2**(P(first was even)+P(first was odd))=1/2(1)=1/2.

## What is the probability of rolling a 7 or 11 with two dice?

The probability of winning on the first roll is the probability of rolling 7 or 11, which is 1/6 plus 1/18, which equals to **2/9**. Suppose we roll 4 on the first roll (the probability of rolling 4 is 1/12). On each successive roll the probability of rolling 7 is 1/6 and the probability of rolling 4 is 1/12.

## What is the ratio of rolling a 2 to rolling a 5?

## What is the formula of probability?

P(**A**) is the probability of an event “A” n(A) is the number of favourable outcomes. n(S) is the total number of events in the sample space.

## What is the probability of rolling an odd number?

The probability when rolling a regular six-sided dice that the score is an odd number is **three-sixths or three out of six**.
