Currently, you have $100. You go to play a game.
Each time, flip a coin, which appears head with probability 0.75, appears
tail with probability 0.25.
Each time, you can bet x dollars, if it's head, you get x , if it's tail,
you lose x.
You can play 10 times. What's the maximum expected payoff after 10 times?
