Find the probability of rolling the difference of 3

To find the probability of rolling a difference of 3, we need to know what kind of dice we're rolling. For example, if we're rolling two six-sided dice (which is common), we would need to find all the outcomes where the difference between the two dice is 3.

Here are the possible outcomes:

(4,1), (5,2), (6,3), (1,4), (2,5), (3,6)

That's 6 outcomes.

The total number of outcomes when rolling two dice is 6*6 = 36 (because each die has 6 sides, and we're rolling 2 dice).

So the probability of rolling a difference of 3 is the number of successful outcomes divided by the total number of outcomes:

P(difference of 3) = 6/36 = 1/6.
