The question should ask about the probability not the odds.

There are 13 spades, the probability that the spade we already have is an ace is therefore 1/13.

Answer: C.

Bunuel, if the question were about odds, the correct answer would be 1/12. Is that right?

Hi Temurkhon,
When talking about odds (in favour) , it is 1 to 12 (or 1:12) as it measures the likelihood of an event occurring posited against not occurring.

You have 13 cards of each suit, hence 4*13 = 52 cards. You have one ace of each suit, probability that first card is ace: 4/52 = 1/13.

This would change if the question asked e.g. "what is the probability that the first card is an ace of spades"
