DH has tried to explain this repeatedly, but with no success (it's too much like a "crooked bellboy" problem, and my math phobia kicks in). Anyone out there want to do a lot of work for 2 lousy points, keeping in mind that you'll have to keep it at about a grade school level so I can understand it? Or point me towards a site that can go verrrrryyyyy sllooooooowwwly? Thanks!

This is really a card game question but since no one there knew the answer I figured I'd ask it here. If 4 cards are dealt from a standard 52 card deck, what are the chances that the 4 card hand will contain at least one Ace and at least one 2. Also, what is the formula for figuring the anser out.
