[charlieeppes.livejournal.com]

Charlie is surrounded by a stack of old books, crumpled pieces of paper, and pencils. He's writing eagerly on one of the blackboards. The heading he's written is: Probability Calculation: Migrasjon.

He waits until everybody in a group has arrived. "Joan Girardi and Kimberly Shaw are no longer enrolled in this class and have possibly been eaten. This means that there's an open place in Intermediate, if you know of anyone who might wish to join us.

This is the attendance I have counted thus far, please let me know if I have made any mistakes." He gives them all a copy of their attendance record, as well as todays problems.

Two players bet on the total roll of two standard dice.  Player A bets that a 12 will be rolled first.  Player B bets that two consecutive 7s will be rolled first.  The players keep rolling until one player wins.  What is the probability that A will win?

Sir, I think... well, I know you didn't make a mistake on attendance, but I think I may have forgotten to sign the roster last friday.

"Sir" Looking at her record "I think I have been in two classes. One where I said what my favorite number was and why and the other one where we had to find out what was important about our numbers, My numbers were 3 and 7."
