25%
13 spades/52 cards= 25%

Please see the homework guidelines:

You should at least show an attempt on your part to do your own work.

Here's a hint to get you started - the probability of getting at least one spade is 1 minus the probability of getting no spades. Remember that after you pull the first card there are only 51 cards left to pul the second card from. Hope this helps.
