What is the probability of rolling doubles on 10 sided dice?
You have a 100% probability to get one result: 10∗110=1. There is also ten possible results for two of the same number in two rolls (1-1, 2-2 etc.), but with 110∗110=1100 chance of each. Therefore the chance of rolling any two equal numbers is 10∗1100=110.
What is the probability of rolling a 10?
P(A) is the probability of rolling a 10. This is 3/36 as there are 36 possible rolls, three of which sum to 10.
What is the probability that the dice show the same numbers?
The second roll of the dice has to match the outcome of the first, so that has a probability of 1/6. The probability of both events occurring is 1 * 1/6.
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.

|Conditional Probability||P(A | B) = P(A∩B) / P(B)|
|Bayes Formula||P(A | B) = P(B | A) ⋅ P(A) / P(B)|
What is the probability of rolling two even numbers?
P(E)=636=16. Probability of two different even numbers = Probability of both even * Probability of both different given they are both even. Probability of both even is 12×12=14.
What is the probability of rolling a 4?

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.
