Gamblers Always Win - Round 1Discrete Mathematics Level 2
Scrooge, who was on vacation, decided to exploit this even value game. He has an infinite bankroll (money) and decides to play the first round (entire series) in the following manner:
He first makes a bet of \( $10 \).
If he wins, he keeps his earnings and leaves.
Each time that he loses, he doubles the size of his previous bet, and plays again.
Now, what is the expected value of Scrooge’s (total) winnings from this first round (which ends when he leaves)?
A "round" refers to the entire series of games played above. This question refers to the entire round. There are 4 rounds in the set of problems.
This problem is part of Go Big Or Go Home, which explores the linearity of expected value.
