Assuming aces are lower than 4 then you have Ace, 2 and 3 each of which are repeated 4 times (as there are 4 different suits). So you have a total of #3times4=12# cards that you can pick which are less than 4. A deck has has 52 cards so the probability of randomly drawing a card less than 4 will be:

#P=12/52 = 3/13#

i.e. a 3 in 13 chance.
