What Is Unbiased and Biased Coin?
Curious as to what what Is Unbiased and Biased Coin implies? Read our breakdown and key takeaways.
An ideal unbiased coin might not correctly model a real coin, which could be biased slightly one way or another. After all, real life is rarely fair. This possibility leads us to an interesting mathematical and computational question. Is there some way we can use a biased coin to ef・…iently simulate an unbiased coin?
What do you mean by unbiased coin toss?
When we talk about a coin toss, we think of it as unbiased: with probability one-half it comes up heads, and with probability one-half it comes up tails. An ideal unbiased coin might not correctly model a real coin, which could be biased slightly one way or another.
What’s the procedure for tossing a coin twice?
Von Neumann described this procedure like this: Toss the coin twice. If the outcome of both coins is the same (HH or TT), start over and disregard the current toss. If the outcome of both coins is different (HT or TH), take the first coin as the result and forget the second.
