Expected value while fishing
You and your friend Jeremy are fishing in a pond that contains 10 trout and 10 sunfish. Each time one of you catches a fish, you release back into the water. Jeremy offers you the choice of two different bets.
Bet 1: If the next 3 fish that he catches are all sunfish, you will pay him $100, otherwise he will pay you $20.
Bet 2: If you catch at least 2 sunfish of the next 3 fish that you catch, he will pay you $50, otherwise you will pay him $25.
What is your expected value from Bet 1?
