Probability of rolling 1 number on both dice: 1/6 * 1/6 = 1/36
Since there are 6 numbers possible (two 1s, two 2s, etc), multiply by 6
1/36 * 6 = 6/36 = 1/6
Ans=E

Probability of the first event : 1
The number could be anything from 1 to 6, but the fact is, the event is certainly going to occur and therefore the probability for the first event is 1.
Probability of rolling the second die and getting the number rolled the first time : 1/6
Combined probability of the two events : 1 * 1/6 = 1/6
