Mr. Amrein, an eighth grade teacher at a Chicago public school, probably never thought that he would receive a personal letter from a Bears player. But after a student named Casey Bridge approached cornerback Charles "Peanut" Tillman at a fundraiser with a question about a specific math problem.

"The Packers play the Bears 4 times in two seasons. The Packers, being a much better team, have an 80% chance of winning each game. What is the probability that the Bears win all four games? What is the probability that the Bears win at least one game?"

Obviously, as a Bears player for nine seasons, Tillman didn't appreciate the problem one bit. In fact, "Peanut" even wrote him a letter to express his dislike and even put in a little threat at the end (see Picture 2).

Mr. Amrein,

This is Charles "Peanut" Tillman of the Chicago Bears and I'm shocked that you would have a problem like this for your students. The probability that the Bears would win in my opinion is 100%. Please do not and I repeat DO NOT send them home with math homework that is disrespectful to our team, city and our beloved Chicago Bears.
