Flipped 3 pennies and did this 100 times. You got 3 tails 40 times. What is the difference between the experimental probability of getting 3 tails and the theoretical probability? (simplified fraction) do it like a 7th grader

1 answer

First find the experimental probability by dividing the number of times you got 3 tails (40) by the total number of trials (100).

Experimental probability = 40/100 = 2/5

The theoretical probability of getting 3 tails when flipping 3 pennies is (1/2)^3 = 1/8.

To find the difference between the experimental and theoretical probabilities, subtract the theoretical probability from the experimental probability:

2/5 - 1/8 = 16/40 - 5/40 = 11/40

So, the difference between the experimental probability of getting 3 tails and the theoretical probability is 11/40.
