A Local Street Vendor Asks His Customer If She Would

Essay

A local street vendor asks his customer if she would like to play a game of chance. The vendor has a jar filled with 100 marbles. Of the 100 marbles, 90 are colored black while 10 are colored red. The vendor says that he'll reach in and pick a marble at random. If the marble is black, the street vendor will pay his customer $1, but if the marble is red the customer will pay the street vendor $5. The picked marble is replaced after the game is finished. If this game is played indefinitely, is it more beneficial for the street vendor or the customer? Explain.
