**Steve**, Saturday, February 2, 2013 at 5:09pmthere are 4 kings in 52 cards, so the chance of picking a king on the 1st draw is 4/52 = 1/13

Now there are only 51 cards, with 3 kings left. SO, the chance of picking a king on the 2nd draw is 3/51 = 1/17

So, the chance of picking two kings in a row is 1/13 * 1/17 = 1/221

No idea what a "deck of six standard cards" is.

If I have misunderstood the question, apply the logic above to the real problem.
