Three cards are drawn without replacement from a well-shuffled deck of 36 playing cards. What is the probability that the first card drawn is a heart?

Question

anonymous · Answer

depends on how many hearts are in the 36 card deck
most decks i know have 52 cards

anonymous · Answer

but if we assume that one quarter of them are hearts, then the probability the first card is a heart is $\frac{1}{4}$

anonymous · Answer

$$\frac{\heartsuit}{\heartsuit+\spadesuit+\clubsuit+\diamondsuit}=\frac{1}{4}$$

anonymous · Answer

I think it's supposed to look like the (A U B) problems, according to the book.
 I just have a problem with setting things up from a word problem.

anonymous · Answer

no, it is just the ratio of the number of hearts to the total number of cards
