Liz flips a coin 50 times. The coin lands heads up 20 times and tails up 30 times. Complete each statement The theoretical probability of the coin landing heads up is %. (Type an integer or a decimal) A​

Explanation:

Assuming we have a fair coin, there's a theoretical 50% chance of getting heads. This is because 1/2 = 0.50 = 50%

This is in contrast to the empirical probability Liz gets which is 20/50 = 0.40 = 40%. The empirical probability is often different from the theoretical probability; however, the two should be fairly close. The empirical probability should also get closer to the theoretical one as you do more trials. For more info, check out the law of large numbers.
