If you're drawing 5 cards, and all 5 have to be in the subset of 10, then we can stop at your second draw and lump it in with all the others that don't meet the criteria. Unless I'm misunderstanding your question, we don't need to worry about any odds once we've drawn a "missed" card. --Ben ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Discover CFTicket - The leading ColdFusion Help Desk and Trouble Ticket application http://www.houseoffusion.com/banners/view.cfm?bannerid=48 Message: http://www.houseoffusion.com/lists.cfm/link=i:5:142584 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/5 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:5 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=89.70.5 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
