Answer:
Step-by-step explanation:
experimental probability is the probability of an event occuring when we perform an experiment.
It goes according to the results of the experiment, not the theory behind it.
<u>Probability of landing tails up, therefore, is the number of times it came tails up divided by the total number of times the coin was flipped.</u>
