Two teams A and B played football twice. Two independent matches. The average shoot of A in match 1 is greater than B. The average shoot of A in match 2 is also greater than B. So can we say the average shoot of A is greater than B in two matches together? If so, why? If not, give me an example. -------- Failed to give the example, but I believe that the statement is not right.

Best of 7 game series between two teams, A and B. You get even odds on both teams for each game and you have to work out how much to bet on each game so that you win $100 if A wins the series and lose $100 if B wins the series and specifically how much you bet on the first game.
