If the bookmakers who run sports betting operations were to set fair odds, so that both the house and those placing bets had expected values of zero, then the probabilities for all of the players should sum to 1, but they don't. Do they sum to a higher or lower value, and why?

Question 2

Answer to Question 1

FOR THE BOOKMAKERS TO MAKE MONEY, THEY SET THE ODDS SO THAT THE PROBABILITIES OF ALL THE PLAYERS SUM TO A NUMBER GREATER THAN ONE. SINCE SO MANY PEOPLE WILL BE PLACING BETS, THE BOOKMAKERS' WINNINGS SHOULD BE CLOSE TO THE EXPECTED VALUE SET BY THE ODDS.

Answer to Question 2

OVERESTIMATE
