FAQs for Unfair Coin Problem

What is an unfair coin?

We've got a fantastic riddle for you this week about an unfair coin. The problem was first posed by Hungarian-American mathematician John von Neumann, and it reveals that this lopsided coin could be more useful than it first appears. Imagine you have an unfair coin, one that does not land on each side 50 percent of the time.

How do you know if a coin is fair?

A fair coin, when tossed, should have an equal chance of landing either side up. In probability theory and statistics, a sequence of independent Bernoulli trials with probability 1/2 of success on each trial is metaphorically called a fair coin. One for which the probability is not 1/2 is called a biased or unfair coin.

What are the possible outcomes when you flip a coin?

a) If you flip a coin once, what are the possible outcomes? Either Heads or Tails right? If you flip a coin twice, the possible outcomes are: (H,H), (H,T), (T,H), (T,T). Where "H" stands for "heads" and "T" stands for "tails" and where (H, H) means that the outcome of the first coin flip was heads, and the second coin flip was also heads.

What are fair results from a biased coin?

Fair results from a biased coin. If a cheat has altered a coin to prefer one side over another (a biased coin), the coin can still be used for fair results by changing the game slightly.
