A. 17/30
B. 30
C. 5/6
D. 1/10

Answer 1

The answer is C=5/6

Answer 2

can you explain how do you get 5/6

Answer 3

count

Answer 4

I am drawing for you to explain you in a bit.

Answer 5

ok

Answer 6

count the number of entries in the table that are less than 10
then put that number over 36

Answer 7

you add numbers which are below "10", so suppose you throw a dice you get "6" on one dice and "4" on another dice, you will ignore that because the sum is 10. Therefore just count ones which are less than 10, there are total 30 occurrences whose sum is less than 10 out of total 36, and probability would 30/36 which is 5/6
