Answer:
Number of times an event occurs : Total number of times the activity is performed
Explanation:
Experimental probability is the probability of an event occurring based on actual experimental results, whereas theoretical probability is the expected probability of an event occurring.
For example, the theoretical probability of flipping a coin and it landing on a head is 1/2.
If we carried out an actual experiment where we flipped the coin 20 times, recorded the results, and only 5 of the flipped coins landed on heads, then the experimental probability of the coin landing on a head would be 5/20 = 1/4.
The more trials we carry out, the closer the experimental probability gets to the theoretical probability.
Therefore, the best definition of experimental probability is:
Number of times an event occurs : Total number of times the activity is performed
