Congratulations, this is my 10,000th answer.


The odds in favor are expressed as [the number of favorable outcomes]:[the number of unfavorable outcomes] and then divide out any common factors.


In a 52 card deck there are 4 suits, so 52 divided by 4 is 13 -- hence there are 13 hearts.  52 minus 13 is 39, so there are 39 cards that are not hearts. So if drawing a heart is considered a favorable outcome, then there are 13 possible favorable outcomes, and there are 39 possible unfavorable outcomes.  Hence, the odds in favor of drawing a heart are 13 to 39.  But notice that both 13 and 39 are evenly divisible by 13, so reduced to lowest terms we have 1 to 3.
