Question

A pair of dice is thrown once. Find the probability of getting a total of 9

Answer 1

Answer:

$\Large{\underline{\underline{\bf{SoLuTion:-}}}}$

Step-by-step explanation:

When a die is thrown the outcome can be any of the numbers from 1 to 6.

If two dice are thrown the set of outcomes that ensure the sum is 9 is

{(3, 6), (6,3), (4, 5), (5, 4)}.

The total number of possible outcomes is 6*6 = 36

This gives the required probability as 4/36 = 1/9

Answer 2

Answer:

1/9

Step-by-step explanation:

(3,6) , (4,5) ,(5,4) ,(6,3)

total number of posibilities (S)= 36

probability of getting sum as 9 (N)=4

hence ,

S/N = 36/9

1/9
