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

**Solution:**

Given, two dice are thrown at the same time.

We have to determine the probability that the difference of the numbers on the two dice is 2.

When 2 dice are thrown at the same time, the overall possible outcomes are

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

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

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

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

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

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

Total number of possible outcomes = 36

Favourble outcomes to get difference of the numbers on the dice as 2 are

(1,3)

(2,4)

(3,1)(3,5)

(4,2) (4,6)

(5,3)

(6,4)

Number of favourable outcomes = 8

Number of possible outcomes = 36

Probability = number of favourable outcomes / number of possible outcomes

Probability of getting difference of the numbers on the dice as 2 = 8/36

= 4/18

= 2/9

Therefore, the probability of getting the difference of the numbers on the dice as 2 is 2/9.
