The experiment involved tossing three coins simultaneously. The experiment was carried out 100 times, and it was noted that three heads occurred 20 times. What is the difference between the experimental probability of getting three heads and its theoretical probability? Write the answer in the simplest form of fraction.

Answer 1

The theoretical probability of getting three heads when tossing three coins simultaneously is 1/8 (since there are 8 possible outcomes and only one favorable outcome).

The experimental probability of getting three heads is found by calculating the number of times three heads occurred divided by the total number of trials. In this case, it is 20/100 = 1/5.

The difference between the experimental probability and the theoretical probability is:

1/5 - 1/8 = 8/40 - 5/40 = 3/40

Therefore, the difference between the experimental probability of getting three heads and its theoretical probability is 3/40.
