4. 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) show ur work

Answer 1

Experimental Probability:
Probability of getting 3 tails = Number of times 3 tails was flipped / Total number of trials
= 40 / 100
= 0.4

Theoretical Probability:
Probability of getting 3 tails = (1/2)^3
= 1/8
= 0.125

Difference = Experimental Probability - Theoretical Probability
= 0.4 - 0.125
= 0.275

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