Henry rolls 2 number cubes numbered 1 through 6 while playing his favorite board game. He will get a second turn if he rolls a sum that is an even number less than 10. What are Henry's chances of getting a second turn when he rolls the number cubes? A. 7/18 B. 11/18 C. 5/36 D. 17/36

Answer 1

a. 7/18

Explanation:

The total number of combinations for dice are 36, given that they can be repeated. And the even number before 10 are 2,4,6 and 8. The ways to get those are:

2:(1,1)

4:(1,3)-(3,1)-(2,2)

6:(3,3)-(1,5)-(5,1)-(4,2)-(2,4)

8:(4,4)-(5,3)-(3,5)-(6,2)-(2,6)

The total number of possibilities are 14, therefore 14/36=7/18
