What is the probability of obtaining a sum of 7 or 5 if two dice are thrown?

In throwing two dice the favorable cases of getting the sum as 7 are: (1, 6), (6, 1), (2, 5), (5, 2), (3, 4), (4, 3). Therefore, the required probability is 6/36 or 1/6.

What is the probability that the sum of two dice is 5 or 7?

Since there are 6 * 6 = 36 possible rolls of two dice, there are 18 rolls whose sum is even. So there are 6 possibilities for the sum to be 7. Thus, there are 18 + 6 = 24 possibilities for the sum to be even or 7. This gives a probability of 24/36 = 66.6%.

What is the probability of getting a sum of 7 when rolling two dice?

For each of the possible outcomes add the numbers on the two dice and count how many times this sum is 7. If you do so you will find that the sum is 7 for 6 of the possible outcomes. Thus the sum is a 7 in 6 of the 36 outcomes and hence the probability of rolling a 7 is 6/36 = 1/6.
