For those who follow the NFL, and in particular the NFC North, you will know that the Chicago Bears and the Green Bay Packers have a heated rivalry. The Bears' Pro-Bowl cornerback Charles "Peanut" Tillman has been a part of that rivalry for his entire NFL career, so it's no wonder he didn't appreciate a certain math problem with a Packers and Bears theme.
As Tillman was promoting his Cornerstone Foundation at a Chicago running store, he was approached by teenage girl who showed him her homework with the following 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?

I wonder if the Bears would win 100 percent of the time, as Tillman suggests, is the correct answer to this problem?
