Assuming Probability

Several students conducted a simulation where a standard coin was tossed several times and the results were recorded in the table. Which table shows an experimental probability of landing on tails that is closest to the theoretical probability of landing on tails?

• A

• B

• C

• D

When calculating experimental probability, as more trials are conducted, the experimental probability generally gets closer to the theoretical probability. Eventually, the experimental probability will equal theoretical probability.

• True

• False
