How many times can you roll a 7 with 2 dice?
When two dices are rolled, there are six possibilities of rolling a sum of 7 .
What is the probability of rolling a total of 7 with two dice at least once in 10 rolls?
With the help of a calculator we find that we will not get a total of 7 on any of the first 10 rolls approximately 16.15% of the time. This implies that we will get a total of 7 on at least one of the first 10 rolls 100%−16.15%=83.85% of the time.
What is the ratio of rolling a 2 to rolling a 5?

What are the outcomes of rolling 2 dice?
Note that there are 36 possibilities for (a,b). This total number of possibilities can be obtained from the multiplication principle: there are 6 possibilities for a, and for each outcome for a, there are 6 possibilities for b. So, the total number of joint outcomes (a,b) is 6 times 6 which is 36.
What is the probability of rolling a sum of 7 or 11 with two fair dice?
What is the probability of rolling a sum of 7 or 11 with two dice? So, P(sum of 7 or 11) = 2/9.
