A coin is flipped 30 times. It landed heads up 9 times and tails up 21 times. Whis is the theorectical probability of the coin landing heads up?

Since it's a fair coin, the probability is of 50%, which equals 15 heads up and 15 heads down.

But, during the experimental probability, the results just happened to be deviated, since we only EXPECTED 15 heads up.


Hope it helped,
