although it might seem odd initially,
P(2nd card is an ace) is exactly = 4/52 = 1/13 <
this is because a card has no preference for position !
still, let us verify conventionally using law of total probability
P(2nd is an ace) = P(aceace) + P(nonaceace)
= 4/52*3/51 + 48/52*4/51
= 4*(3+48)/(52*51) = 4/52 = 1/13 <

if first removed card is not an ace
P=4/51
other wise
P=3/51=1/17

If the card on the top was an ace then it's 3/51, otherwise it's 4/51. So it would be a probability of 7/102.
