The experiment involved tossing three coins simultaneously. The experiment was carried out 100 times, and it was noted that three heads occurred 40 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.(1 point)
Experimental probability of getting three heads = Number of times three heads occurred / Total number of trials = 40 / 100 = 2/5
Theoretical probability of getting three heads = Probability of getting head on one coin toss * Probability of getting head on second coin toss * Probability of getting head on third coin toss = (1/2) * (1/2) * (1/2) = 1/8
Difference between experimental and theoretical probability = 2/5 - 1/8 = 16/40 - 5/40 = 11/40
Therefore, the difference between the experimental probability of getting three heads and its theoretical probability is 11/40.
