Probability of getting a 10 or a 11 when a pair of dice are rolled?

In summary, the probability of getting a 10 or 11 when rolling a pair of dice is 11.11%. This probability remains the same even when rolling with two dice, as long as both dice are equally biased. However, if one die is already known to be a 5, the probability of getting a 10 or 11 on the second die increases to 33.33%.

Since we're looking for 10 OR 11, it means we just need to add the probabilities of finding each separately. So what are the odds of finding a 10? And then what about 11?

Depending on how you've been taught so far to do probabilities, one way would be to use a tree diagram.
 

FAQ: Probability of getting a 10 or a 11 when a pair of dice are rolled?

What is the probability of getting a 10 or 11 when rolling a pair of dice?

The probability of getting a 10 or 11 when rolling a pair of dice is 4 out of 36 possible outcomes, or approximately 11.11%. This can be calculated by dividing the number of favorable outcomes (4) by the total number of possible outcomes (36).

How is the probability of getting a 10 or 11 affected by rolling with two dice instead of one?

Rolling with two dice increases the number of possible outcomes from 6 to 36. This means that the probability of getting a 10 or 11 when rolling with two dice is lower than when rolling with one die, but it is still 11.11%.

What is the probability of getting a 10 or 11 when rolling two dice that are not fair?

The probability of getting a 10 or 11 when rolling two dice that are not fair depends on the specific biases of the dice. If one die is more likely to roll a certain number than the others, the probability will be affected. However, assuming both dice are equally biased, the probability will still be 11.11%.

Is it possible to get a 10 or 11 when rolling two dice that are not fair?

Yes, it is possible to get a 10 or 11 when rolling two dice that are not fair. The probability may be lower or higher than 11.11%, depending on the specific biases of the dice.

How does the probability of getting a 10 or 11 change if one die is already known to be a 5?

If one die is already known to be a 5, then the probability of getting a 10 or 11 when rolling the second die is 2 out of 6, or approximately 33.33%. This is because there are only two possible outcomes (5 and 5 or 5 and 6) out of the six possible outcomes when rolling a single die.
