The first card is a spade. So there are 13-1 = 12 spades left. On the second draw, there are 52 - 1 = 51 cards left.

So the probability of drawing a second spade given that the first is a spade is 12/51 = 4/17

-----------
Once you have removed the 1st spade, there are 12 left.
P(draw spade after spade drawn) = 12/51
