You and I will play a game. I lay out N coins of different denominations (i.e. nickels, dimes, quarters, pennies) in a straight line across the table. We each take turns choosing one coin from either side of the line - meaning, you can only choose one of the end coins. We keep picking coins until none are left. The winner is the person whose sum of coins is the greatest. I let you decide if you go first or second. Do you wish to go first or second? And what is your strategy?

Bag with 100 coins. One of them is double headed, the rest are fair. You flip it n times and get n heads. What would your intuition be on whether you have the double headed coin or not? What would the probability be that you have the double headed coin be as n goes to infinity? How many flips would it take for you to be 50% sure? You flip it seven times, what is the probability you have the double headed coin?
