1. Talisa assigns a number to each of her 5 guests, numbers 1-5, so they can have a chance to win door
prizes at her party. She writes the numbers on
separate pieces of paper and drops them into a bag.
She reaches into the bag and pulls out 1 number,
then puts it back. Talisa then reaches in and pulls out
a number again. What is the probability that she pulls
out the same number 2 times?
A. 1/25
B. 1/20
C. 1/10
D. 1/5

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.)
