What is the probability of rolling a number cube and getting an even number or a multiple of 3?

I got 4/6 as the probability, but that isn't a choice. 6 is a multiple of 3 and an even number, so if I count 6 once, then I get 4/6 as the probability. But if I count 6 twice (for being an even number and a multiple of 3) then I get 5/6 as the probability, which is a choice. So would the answer be 5/6?
