Interesting question: From a deck of 52 cards pick 26 at random. From this set of 26 you pick two cards. You win if the both of these cards are of the same color. Is this a game you would prefer over one in which you win by picking two (first two picks) of the same color at random from a deck of 26 with equal number of black and red cards

You have 9 digits 1-9. Partition them into two sets S1 and S2. Make a number (any) using the digits of partition S1. Call this x. Similarly do it for S2. Call it y. the product p=xy. What should the numbers x and y be to maximize p.
