Question

why we will take 36 outcomes in this question​

Answer 1

Answer:

25 / 36

Step-by-step explanation:

When a die is thrown twice means it is same as 2 dice thrown at once so

The 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 outcomes = 36

Number of desirable outcomes = 25

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

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

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

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

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

Probabilityof 5 will not come up either time = Number of desirable outcomes / number of total outcomes

= 25 / 36
