Henry goes to a casino in Las Vegas with $5120 to play a game called "Double or Nothing". He always puts up half of his money for a bet. He bets 10 times, out of which he wins 5 times and loses the other 5 bets but we do not know in what order. How much money could he possibly have at the end?
this seems preety easy to me he would en with 5120
However, if he wins and loses both five times, then he would walk away with the original amount he had: $5120. Order does not matter.
