Question

While you are waiting for your nets to fill, you play the following game: you have two coins, one is fair (heads/tails with equal probability), one is biased (heads twice as likely as tails). The coins are otherwise identical. You are going to choose a coin at random, flip it N many times, and then try to decide based on the results whether the coin is the fair coin or the biased coin. You win the game if you correctly identify the coin. (Your robot cat is able to distinguish which coin is which, and scores the game.)

You decide to follow the following strategy: if the majority of the flips are heads, you’ll guess it is the biased coin, otherwise you’ll guess that it is fair. That is, you’re setting a threshold of N/2 such that if you get that many heads or more, you guess it is the biased coin, otherwise you guess it is the fair coin.

1)  Following this strategy, what’s the probability you win in a game of 10 flips? 20 flips?

2)  If you want to maximize your probability of winning, what threshold should you set for your strategy in a game

of 10 flips? 20 flips? Be thorough as to your methods, and precise.
