Coin Toss Bias and Fairness

The video explores the fairness of coin tosses, revealing a slight bias in human coin flipping. A 2007 study found a 51% chance of a coin landing on the same side it started. A large experiment confirmed a 50.8% bias, despite coins being fair. Practical advice includes betting on the same side and hiding the starting face. The video concludes that coin flipping is not entirely fair due to this bias.
