I have no familiarity with playing cards, but I found these questions on my math homework:
What is the probability of drawing an ace or a deuce from a standard deck of cards?
What is the probability of NOT drawing an ace or a club from a standard deck of 52 cards?
Thanks.
If you have no familiarity with playing cards, as you say, then there are better ways of remedying the situation than posting here. No offence intended 
Look up “playing cards” in a dictionary, or on Google. That ought to tell you how many cards are in a pack, and how many of them are aces. Then you ought to be able to work out your homework. Also remember that if you know the probability of picking an ace, you ought to be able to figure out the probability of not picking one.
Good luck.
There are 52 cards in a deck, with four aces and four deuces.
You do the math.
In brief: we don’t do your homework here.
You know better than that.
As has been pointed out . . . we will not do your homework for you, Themis00.
