A catering company offers three monthly meal contracts: Contract A costs a flat fee of $480 per month for 90 meals;
Contract B costs $200 per month plus $4 per meal;
Contract C costs a straight $8 per meal.
If you expect to eat only 56 of the available meals in a month, which contract would be best
for you? When might someone prefer contract A? contract B? contract C?

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.)
