Probability Puzzlers - Fall 2011

At various times during the semester, I posted a ``Probability Puzzler'' on this page. Those who submitted a valid solution were entered into a draw for a small weekly prize.

Two people (Sean Meehan and Gabe Schepergerdes) solved all 9 puzzles correctly. They both won a slightly larger prize at the end of the semester.

• Puzzle 1 (Friday, August 25; solutions by Wednesday afternoon, August 31)
• Puzzle 2 (Friday, September 2; solutions by Wednesday afternoon, September 7)
• Puzzle 3 (Friday, September 9; solutions by Wednesday afternoon, September 14)
• Puzzle 4 (Friday, September 16; solutions by Wednesday afternoon, September 21)
• Puzzle 5 (Friday, September 23; solutions by Wednesday afternoon, September 28)
• Puzzle 6 (Friday, October 6; solutions by Wednesday afternoon, October 11)
• Puzzle 7 (Friday, October 28; solutions by Wednesday afternoon, November 2)
