Brett has a box of sports cards. the box has 12 soccer cards, 15 baseball cards, 8 boxing cards, and 10 basketball cards. what is the probability of randomly selecting a baseball card from the box?

I'll do it with a fraction, so let's say 15/45. 15 of the cards are baseball cards, 30 of them are other cards. I would say 15/45, because 45 is the total amount of the cards he has. Only 15 are BASEBALL cards, so it would make sense to say he has a 15/45 chance to pull a baseball card.

The probability of selecting a baseball card is 15/45 which is simplified to 1/3

Im sorry but what on
