PPT-Flipping A Biased Coin

Suppose you have a coin with an unknown bias θ Phead You flip the coin multiple times and observe the outcome From observations you can infer the bias of the coin Maximum Likelihood Estimate. An ideal unb iased coin might not correctly model a real coin which could be biased slightly one way or another Afte r all real life is rarely fair This possibility leads us to an interesting mathematical an d computational question Is there some wa minting . first . started around the 7th century B.C. in Asia Minor and quickly spread east and west. .
