What are the odds of rolling an odd number or a number divisible by 3 in a single roll of a fair die?
When a fair die is thrown, the probability of getting each of the digit 1,2,3,4,5 and 6 is 16 . Of these, digits divisible by 3 are 3 and 6. Hence when you roll a fair die once, probability of getting a number divisible by 3 is 26 or 13 .
You are watching: A fair die is rolled. what is the probability of rolling an odd number or a number less than 3?
What is probability of getting a number divisible by 3?
We know we are looking specifically to get a 3, 6, 9, 12, or 15 each time, so there are 5 possible numbers which would give us that “success.” Altogether, there are 7 numbers in the list, so the chance of getting a number that’s divisible by three is 5/7.
When a die is thrown what is the probability of getting the number 7?
Probability of getting a number What is the probability of getting 6 when a die is thrown?
What is the probability of rolling the same number 3 times?
Rolling any number on a dice three times in a row is equal to the number of throws 1/6^3*6 = 1/36, where 3 represents the number of throws and 6 is the number of different ways to get three of the same number (e.g. 1, 1, 1 2, 2, 2 3, 3, 3…).
What are the odds of rolling a 1/3 times in a row?
1 Answer. The probability is 1216 chance, which is approximately a 0.46% chance.
What is the probability of rolling 6 sixes in a row?
Rolling a six on your next roll does not depend on whatever you rolled before. The die has no memory. That is different from predicting ahead of time that you’ll roll six straight sixes; that probability is (1/6)6, but each individual roll still has a probability of 1/6.
What is the probability of getting a sum of 8 or 14 when rolling 3 dice simultaneously?

What is the probability of rolling a 3 or 8?
The total number of ways to roll an 8 with 3 dice is therefore 21, and the probability of rolling an 8 is 21/216, which is less than 5/36. heads out of 20 is (20 10 ) /220 ≈ 17.6%.
What is the probability of rolling a sum less than 10?
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 a sum greater than 10?
Since there are a total of 6 x 6 = 36 outcomes, then the probability that the sum will be greater than 10 is 3/36 = 1/12.
What is the probability of rolling a sum greater than 7?
A sum greater than 7 occurs when the total is 8,9,10,11 or 12. The probability of obtaining a sum greater than 7 is 15/36 = 5/12 or approx 0.42.
What is the probability of rolling a sum less than 5?
If two dice are rolled one time, find the probability of getting a sum less than 5. So you are talking about 1,1; 1,2; 2,1; 2,2, 1,3; or 3,1. Each pair has a probability of 1/36.

What is the probability that when you roll two dice the total will be ten?
A lot of it has to do with what perspective you are looking at. If you consider the chart on the webpage given, there are 36 combination of rolls you can get from two dice. When you consider the sum being 10, there are only 3 combinations. So, the probability of getting a 10 would be 3/36 = 1/12.
