Truel

A truel is a three-way duel. The three participants take turns firing one shot at whichever opponent they choose, until only one is remaining.

Allison, Ben, and Chase are in a truel, and have varying degrees of accuracy: Allison has a 50% chance of hitting her intended target, Ben has a 80% chance, and Chase has a 100% chance. Allison gets to shoot first, then Ben, then Chase, and repeating in that order until only one person is remaining.

Assume that the accuracy of all participants are publicly known, and everyone is trying to maximize their chances of winning. What is Allison’s optimal strategy, and what is her likelihood of winning under that strategy?

Missing Dollar Riddle

The missing dollar riddle is a classic brain teaser that can trip up even savvy puzzle solvers:

Three friends split the cost of a hotel room. They are charged \$30, so each of them pays \$10.

Later the hotel manager realized the room only cost \$25 instead of \$30. The manager brings \$5 to reimburse the friends.

The manager finds it hard to split \$5 three ways, so he gives the friends \$1 each, and keeps \$2 for himself.

But wait – each friend paid \$9, for a total of \$27, and the manager pocketed \$2. That’s 27 + 2 = 29, whereas they originally handed over \$30. Where did the missing dollar go?
