## What is the probability of having a sum of 7 when you toast a pair of dice Brainly?

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.

## What is the probability that you would obtain a sum of 7 or a sum of 11 on the first roll?

For example, since a 7 or an 11 is a winner on the first roll and their probabilities are 6/36 and 2/36, the probability of winning on the first roll is 6/36+2/36=8/36.

## What is Possible outcomes in probability?

Possible Outcomes – a list of all the resulting possibilities from an event. e.g. When rolling a die – all possible outcomes are 1, 2, 3, 4, 5, 6. 6. Favorable Outcome – the result that is desired.

## What do you call the set of all possible outcomes of an experiment?

A set of all possible outcomes of an experiment is called a sample space. We shall denote the sample space by S. Hence, that the sample space is simply the set of all possible sample points of a given experiment.

## How many possible outcomes are there for the experiment of choosing rock paper or scissors at random Brainly?

Answer: There are 9 combinations overall in the given situation.

## What is the probability of getting a sum of 7 or 11 are these outcomes mutually exclusive?

= P(A) + P(B) – P(A and B) A pair of dice is rolled. What is the probability that the sum of the numbers rolled is either 7 or 11? The sum of the numbers cannot be 7 and 11 at the same time, so these events are mutually exclusive.

## What is the probability of getting a sum of 2 if a pair of dice is rolled?

The answer is the following: the combinations (1,3) and (2,2) are not equiprobable. We have a probability of 1/6 that the first die rolls 2, and a probability of 1/6 that the second die rolls 2, thus making a combination (2,2) with the probability 1/36.
