Marla noticed that her friend Ron had three times as many pieces of candy as she did. She toldhim, “If you give me seven pieces of your candy, we’ll have exactly the same number ofpieces.” Ron responded, “I didn’t know that until you mentioned it. But I’ll make you a deal: Ifyou can show me how to solve this puzzle using algebra, I’ll give you the seven pieces.”One minute later, Ron was shocked to see that Marla had solved it perfectly. Can you do the same?

Our star pitcher, foster enlight, can throw a pitch so fast that it gets to the catcher’s mitt before it leaves foster’s fingers! if the team wins a game then the probability that foster was pitching is 0.8 but only if foster had at least one day’s rest since his last pitching assignment. if foster does not have a day off and the team still wins, the probability that foster was pitching drops by half of what it was on the previous day. if the team wins three games in succession from the toronto tachyons and foster pitched in game #2, what is the probability that he pitched in one or more of the other games? (assume that foster did not pitch on the day before the first game of this three game series.)
