2 Answers. The probability is 25% .

What is the chance of getting the sum of atleast 7?

So, the sum of the numbers on the dice must be greater than or equal to 7. Here, we can clearly see that the total number of favourable outcomes is 21. Thus, the chance of throwing at least 7, in a single throw, using two dice is 712 .

When two dice are thrown simultaneously What is the probability?

The number of favourable outcomes is the sum of occurrences of all the favourable outcomes. So, the number of favourable outcomes =1+2+4+6+2=15. We know that the number of possible outcomes is 36. Thus, the probability of getting the sum of two numbers as prime numbers is =1536=512.
