Question

Two dice are thrown at the same time
What is the probability that the sum of the two numbers appearing on the top of the dice is8?​

Answer 1

Given :

Two dice were thrown simultaneously

To find :

Probability of getting sum of two number appearing on top = 8

Formula used :

Probability = Favourable outcome ÷ Possible outcomes

Solution :

Total outcome when two coin are thrown = 36

• (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)

Among the above outcome (2,6) , (3,5) , (4,4) , (5,3) , (6,2) are outcome when sum of two numbers appearing on top is 8.

Therefore we have,

• Favourable outcome = 5
• Total possible outcome = 36

Probability = 5/36

ANSWER : 5/36
