Question 62764
Rolling of dice would give the probability of (1/36) of the happening.
It is also given that the difference in the outcome is more than 2.
Let us make a list of it.

First dice |  second dice

 1| 4

 1| 5
 
 1| 6

 2| 5

 2| 6

 3| 6

 4| 1

 5| 1

 6| 1

 5| 2

 6| 2

 6| 3


There are 12 possibilities.

Therefore the total probability is given by = possibilities / total ooutcome = 12 / 36 = 1 /3

The probability that the two numbers obtained differ by more than 2 is 1/3
