Question

In an experiment you are to flip a two sided coin 100 times and record 55 heads up and 45 tails up. Determine the theoretical and experimental probability of getting a heads up in the experiment.

Answer 1

0.55, 0.50

Explanation:

The experimental probabilty would reflect the actual results: 55/100, or 0.55.

The theoretical probability would build on the probability 1/2, or 0.5. The greater number of flips of this coin, the closer the actual probability will be to 0.5, which is how we determine that the theoretical probability approaches 1/2 or 0.5.
