I had a mid-term today.

The test had eight essay questions along with many multiple choice problems. Before the test the professor offered us an option. We could answer 4 of the 8 essay questions (along with the multiple choice questions) or one of us could select an envelope from a set of 9 envelopes containing a number between 0-8. The number in the envelope would be the number of essay questions everyone had to answer.

I convinced the class to select an envelope rather than holding at 4. I was then voted to pick the envelope. Without hesitation I selected an envelope. I should have bought a lottery ticket this morning. I picked the zero. No essay questions for anyone.
