Explain what it means to say that team A has 2/3 probability of beating team B in any one game.
Answer: If these two teams play each other many, many times under identical conditions, team A will win 2/3 of the games in the long run
It would be correct to say that if team A plays team B for 3 games, A guaranteed to win exactly twice.
Answer: False
It would be correct to say that if team A plays team B for 30 games, A guaranteed to win exactly twenty games .
Answer: False
If team A plays team B for 30 games, is it very likely that team A will win exactly 20 times? Explain
Answer: No, the proportion of games that team A wins will likely be close but not exactly 2/3 (such as 18,19,20,21,22 wins), so there could still be a low probability that A wins exactly 2/3 of the 30 games.
