1 red die with faces labelled 1, 2, 3, 4, 5, 6.

2 green dice labelled 0, 0, 1, 1, 2, 2.

Answer: 1/9

Please can you show me how to get the answer. I'm confused about joining the events of choosing 2 of 3 dice vs. getting the probability that one of the dice chosen will get a 6 when rolled.

Note: There is an equi-probable chance of getting any of the six sides on a given die.
