To choose two out of three, three coins are flipped, and if two coins come up the same and one different, the different one loses (is out), leaving two players. To choose one out of three, the previous is either reversed (the odd coin out is the winner) or a regular two-way coin flip between the two remaining players can decide. The three-way ...
It is based on the coin flip used widely in sports and other situations where it is required to give two parties the same chance of winning. Either a specially designed chip or more usually a simple currency coin is used, although the latter might be slightly "unfair" due to an asymmetrical weight distribution, which might cause one state to ...
When flipping a fair coin 21 times, the outcome is equally likely to be 21 heads as 20 heads and then 1 tail. These two outcomes are equally as likely as any of the other combinations that can be obtained from 21 flips of a coin. All of the 21-flip combinations will have probabilities equal to 0.5 21, or 1 in 2,097,152. Assuming that a change ...
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.

Internally, the algorithm consults two tables, a probability table U i and an alias table K i (for 1 ≤ i ≤ n). To generate a random outcome, a fair die is rolled to determine an index i into the two tables. A biased coin is then flipped, choosing a result of i with probability U i, or K i otherwise (probability 1 − U i). [4]
A tied vote for a seat on the Blue Lake City Council was decided by drawing an envelope from a box on Dec. 10. Former City Clerk Karen Nessler, left, did the honors.
A random procedure, such as a coin flip or the roll of a dice, gives equal weight to the preferences of citizens and would therefore appear to be as procedurally fair as a democratic vote. Estlund therefore argues that if we prefer a democratic vote to a purely random decision, then it must be because we expect it to make the correct decisions ...
