Batter Up!
You and a colleague are having a bet on the upcoming National League Championship playoff series.
Since you both think the Phillies will win the series, you bet as follows:
If the Phillies win in four or five games, you win a soda.
If the Phillies win in six or seven games, your colleague wins.
Are the odds even?
If not, who has a better chance of winning?
How do you calculate the odds?
Bonus: can you calculate the odds with an equation?
