Answer:

a. 7/18

Step-by-step 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
