Two dice are thrown simultaneously. What is the probability that the sum of the numbers appearing on the dice is 1

Solution:

Given, two dice are thrown simultaneously.

We have to find the probability that the sum of the numbers appearing on the dice is 1.

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

Number of favourable outcomes = 0

Number of possible outcomes = 36

Probability = number of favourable outcomes / number of possible outcomes

Probability of getting a sum of 1 = 0/36

Therefore, the probability of getting the sum of 1 on the dice is zero.
