Also can be 4C2/52C2 as number of ways to pick 2 aces out of four/number of ways to choose 2 cards from 52.
=1/221
Probability of first ace= 4/52
 
Probability of second ace without replacement = 3/51
 
So , total probability = (4/52)*(3/51)
 
                               =(1/13)*(1/17)
 
                               = 1/221
