Please explain in detail with a proper answer.

Answer 1

Answer:

5/36

Step-by-step explanation:

So a pair of dice is rolled. 2 dices. A dice has 6 numbers (1,2,3,4,5,6).

Now draw a sample space.

 1  2  3  4  5  6

1 2  3  4  5  6  7

2 3  4  5  6  7  8

3 4  5  6  7  8  9

4 5  6  7  8  9  10

5 6  7  8  9  10  11

6 7  8  9  10  11  12

It's asking for SUM, so we plus. Thats why you see this.

So look for all the 8's in the sample space. Theres one in (6,2), (5,3), (4,4), (3,5) and (2,6). Thats 5. We divide that with the total. The total is 36 because there are 36 possible values. so 5/36
