I have a bet with a friend who says that if you have 50 cards with 1 card being the ace of spades which you deal in 5 10 card stacks you then get a 1 in 5 chance of turning the ace of spades instead of a 1 in 50. He gets there by making 5 one card stacks with 1 stack being the ace of spades which would be 1 in 5. He then puts the remainder of the 50 cards in each stack creating 10 cards per stack and argues the chances of turning the ace of spades remains a 1 in 5 chance. I insist that it goes to a 1 in 50 chance. Who is correct and why?//<![CDATA[ aax_getad_mpb({ "slot_uuid":"f485bc30-20f5-4c34-b261-5f2d6f6142cb" }); //]]>
