The probability of getting at least an ace when two dice are rolled is

Find the probability of getting more than 7 when two dice are rolled.

Two dice are thrown together. Then the probability that sum of the two numbers on the dice will be multiple of 4 is:

Two dice are rolled simultaneously.The probability that the sum of the two numbers onthe dice is a prime number is the dice is a prime number is

Two symmetrical dice are rolled.If the number thrown up on them are different,the probability of getting an even number as the sum of the numbers is dice are rolled If no two dice show the
