OK TAFKAS try this one.
You dare not offend nor disappoint Great Uncle Willy lest he disown you. He has placed $2000 in your hands to bet on the outcome of the world series, which is a baseball contest won by whichever of two teams first wins 4 games. Willy’s $2000 was given to you in advance of the series. At the end of the series he expects you to return to him either $4000 if the team he chose wins, or nothing if it loses.
But you can find nobody who will accept bets on the entire world series. However, there are wagerers who will take on even-odds bets, in any amount(s), on each game individually. What strategy for placing bets on individual games will achieve the cumulative result Willy expects?
Note: This task was reputedly set before job-seekers at a Wall Street brokerage.
