## 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 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 that 3 will come up at least once?

For the part (ii), we have to find the probability that 3 will come up at least once. This means that 3 can come upon one of the two thrown die or on both. Therefore, its Probability (P) is: P=Fav.

## What is the probability of getting 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.

## How many different ways can you roll a sum of 10?

The number of ways of getting a sum of 10 is (6, 4), (4, 6), (5, 5). A sum of 10 is obtained 3 times. The number of ways in which either a sum of 5 or 10 can be got is the sum of the individual values for 5 and 10 or 4 + 3 = 7.
