Two dice are thrown at the same time. Determine the probability that the difference of the numbers on the two dice is 2.

Question

Accepted Answer

Step 1: Total outcomes $= 36$
Step 2: Number of outcomes with difference of the numbers $= 2$: $(1,3), (3,1), (4,2), (2,4), (5,3), (3,5), (4,6), (6,4) = 8$
Step 3: $P(	ext{difference} = 2) = \frac{8}{36} = \frac{2}{9}$
