Hi everyone,

Assume that Jack goes to a casino. He plays several games (let's say
5).
Every time he wins a game he gets 100$and every time he looses a game he looses 50$. Below are the probabilities of each time he wins a game
(the
probability reduces every time).

1
1/2
1/4
1/8
1/16

How can we compute the expected amount of money he has won or lost
after he
had played the above five games? Thanks

Best Regards
