To find the experimental probability of getting three heads, we use the formula:
Experimental Probability = Number of times event occurred / Total number of trials
Experimental Probability of getting three heads = 40/100 = 2/5
The theoretical probability of getting three heads when tossing three coins simultaneously is:
The number of favourable outcomes = 1 (HHH)
Total number of possible outcomes = 2^3 = 8
Theoretical Probability = Number of favourable outcomes / Total number of possible outcomes
Theoretical Probability = 1/8
The difference between the experimental probability and the theoretical probability is:
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.
The experiment involves 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)
