In a game of blackjack, if your first card is a spade, what are the odds that it is an ace?

A. 1/52 B. 1/26 C. 1/13 D. 1/4 E. 5/13

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.

I selected A 1/52 ... Really difficult to understand how blackjack is being played with 13 cards.. _________________

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.
