Process
Lots of questions and testing. Brush up on applied probability theory and strange EV questions beforehand. Lots of dice rolling and drawing playing cards. Best of luck to you all.
Questions
Roll 6 dice, add up the scores for each number (sum of 6s, sum of 4s, etc.) until the score of one exceeds 100. What's the EV of all dice at this point?
