What is the probability two die, a red and a white one, show the same values on their second rolls as on their first rolls?
so i first computed the total number of ways of just getting outcomes from two sets of rolls:
now the next step I wanted to perform was to obtain the number of outcomes in which the value obtained on the first roll is obtained on their second rolls:
my reasoning for the $6^2$ is that after we get whatever number for the first set of rolls, the second set doesn't matter. But I feel this just may be too high an outcome because the probability would work out to $0.50$
I am not concerned about finding the probability, I am concerned on performing the combinatorial idea so any feedback there would be helpful. Thanks
