Question

when two dice are rolled, what is the probability the two numbers will have a sum of 10? a. 1/3 b. 1/10 c. 1/18 d. 1/12

Answer 1

Possible values that adds up to 10 with 2 dice.
Values are 4, 5 and 6.
5+5=10
6+4=10

When you roll the 2 dice, you can get 4 THEN 6 or 6 THEN 4. So these are the 2 ways to get 10.

You can also get both numbers 5 so, there are a total of 3 ways to get a sum of 10.

n = number of ways you can get a sum of 10.

n(1/6×1/6)=3(1/6×1/6)=1/12

Hence, answer is d. 1/12.

Answer 2

the answer is 1\12
