​

Answer 1

Answer:

1. 9/36 =1/4

2.5/36

Step-by-step explanation:

two die is thrown

so no. of pair is 36.

even pair is 9.

2) sum of 8

their are 5 pairs who gives 8

Answer 2

Answer:

(1)3/4  (2)5/36

Step-by-step explanation:

total no. of possible outcomes=36

(1) probability of getting an even no. on each dice=27/36=3/4

because   {(1,2),(1,4),(1,6);(2,1);....(2,6);(3,2);(3,4),(3,6);(4,1)....(4,6);(5,2);(5,4);(5,6);(6,1)...(6,6)}

(2)probability of getting a total of 8=5/36

because    {(2,6);(3,5);(4,4);(5,3);(6,2)}
