The experiment involved tossing 3 coins simultaneously. The experiment was carried out 100 times and noted that 3 heads occurred 40 times . What is the difference between the experimental probability of getting 3 heads and it’s theoretical probability.

Answer 1

The theoretical probability of getting 3 heads when tossing 3 coins simultaneously is calculated using the formula: (1/2)^3 = 1/8.

The experimental probability of getting 3 heads is calculated by dividing the number of times it occurred by the total number of experiments: 40/100 = 0.4.

Therefore, the difference between the experimental probability and the theoretical probability is:

Theoretical Probability: 1/8 = 0.125
Experimental Probability: 0.4

Difference = 0.4 - 0.125 = 0.275

Therefore, the difference between the experimental probability of getting 3 heads and its theoretical probability is 0.275 or 27.5%.
