:confused:If you are calculating the probability of getting an odd numbered card in a pack of 52 playing cards, would count ace as an odd number (instead of 1)?:confused:

I would count the ace as a 1 -- and 1 is an odd number. I would say that the odd numbers in a deck are 1, 3, 5, 7, and 9. the face cards would not count -- but an ace isn't a face card.
