The experimental involved tossing three coins simultaneously the expirement 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 it’s theoretical probability write the answer in the simplest form of a fraction
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 one head) * (Probability of getting three heads) = (1/2)^3 = 1/8
Difference = Experimental probability - 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.
