Question

Jan tossed a coin 50 times and got a head 20 times. What is the

experimental probability? What is the theoretical probability?

Answer 1

The standard answer for this is 50%.

Explanation:

However, this is based on the implicit assumption that the coin is fair.

If there are reasonable grounds to doubt that the coin is fair, the theoretical probability must be based on observed statistics. In this scenario, the probability is 60%.
