Question

Check my answer please.

A box contains 15 cards. There are 5 red cards labeled 1, 2, 3, 4, and 5. There are 5 blue cards labeled 1, 2, 3, 4, and 5. There are 5 green cards labeled 1, 2, 3, 4, and 5. One card is drawn from the box.

What is the probability that it is a blue card with an even number or a red card with an odd number?

I think 1/3.
