What is mean by unbiased coin?
Hiii Amarjit,
Unbiased coin means that the probability of heads is the same as the probability of tails, each being 1/2(equal probability of selection),. A coin that has two different sides for two different results,irrespctive of how many trials you do.
Outcomes are not equally likely, they might be equal or might not be equal, it is biased coin.
Thank you !!!
