In a dice roll it has a total of 6 numbers and there’s 2,4,6 which is three numbers that are even. Which leaves out 1,3,5 odd. but if there is two dice rolls that means 6x2=12 and then double the even and odds
3x2=6
So 6/12 are even but the answer to your question would be 2/12 because there’s only one 5 in each cube which makes there two fives in total.
Answer: 2/12
One cube: 1/6
Both cubes 2/12
Hopefully that helps have a nice day!
