• What actually happens
• What should happen
• What I think Happens

• The more times the coin is tossed, the closer the experimental probability will get to the theoretical probability

• The theoretical probability is less than the experimental probability of landing on tails.

• The theoretical probability of landing on tails is 1/2 and the experimental probability of landing on tails is 19/40

• The theoretical probability is the same as the experimental probability of landing on tails.
