Question

Two cubical dice whose faces are number 1 to 6 are rolled simultaneously once . Find the probability that the sum of the two number occuring in their top faces is more than 7

Answer 1

Answer:

welll according to me 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.
