## What is the probability of rolling a 4 on one roll of a die?

Two (6-sided) dice roll probability table

Roll a… Probability
2 1/36 (2.778%)
3 3/36 (8.333%)
4 6/36 (16.667%)
5 10/36 (27.778%)

## What is the probability that the sum will be 4?

Now we can see that the sum 4 will be rolled with probability 3/36 = 1/12, and the sum 5 with probability 4/36 = 1/9. Below you can check our random “roll of dice” generator. It will count for you the total number of rolls and the total for each sum.

## When a dice is tossed the probability of getting 4 is?

(i) Let E1 = event of getting the number 4. Then, E1={4} and, therefore, n(E1)=1. ∴ P(getting the number 4) =P(E1)=n(E1)n(S)=16.

## What is the probability of getting a 4 or 10 if two dice are rolled?

So, then, the probability of getting a sum of 10 with one die being a 4 would be 2/36 = 1/18, when taking into consideration all possible combinations.

## How do you figure out probabilities?

Divide the number of events by the number of possible outcomes.

1. Determine a single event with a single outcome. …
2. Identify the total number of outcomes that can occur. …
3. Divide the number of events by the number of possible outcomes. …
4. Determine each event you will calculate. …
5. Calculate the probability of each event.

## What is the probability of rolling a four or an odd number?

There are two cases, one where you first get the four, or you get an odd then a four. The probability of just rolling a 4 first is 16. If you roll one odd number before the 4, that has a chance of 12∗16 Now, you can roll 2 or 6 infinitely many times and it won’t matter. So, it is a infinite geometric series.

## What is the theoretical probability of rolling a 4?

Answer:If a die is rolled once, determine the probability of rolling a 4: Rolling a 4 is an event with 1 favorable outcome (a roll of 4) and the total number of possible outcomes is 6 (a roll of 1, 2, 3, 4, 5, or 6). Thus, the probability of rolling a 4 is 1/6.

## What is the probability of rolling a sum less than 10?

so I wrote out all the possabilities of combinations of 10 or higher. That totals 8 combination out of 36 that could be ten or higher, so 8/36= 2/9. since I wanted less than ten 1-(2/9) = 7/9 probability of getting less than 10.

## 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.
