Theoretical Probability

8. Compare experimental and theoretical probability

Question:

3 m.

A coin was tossed 30 times, and tails appeared 16 times.

1. The experimental probability of getting a tail is

\(0.9\)
0.533
\(1\)
\(0.5\)

2. The theoretical probability of getting a tail is

\(0.5\)
\(1\)
0.533
\(0.9\)

3. Explain why the experimental probability is different from the theoretical probability.

Theoretical probability is always wrong and experimental probability is always correct.
Because experimental probability can only be a whole number, while theoretical probability can be decimal.
Because experimental probability only applies to coins, while theoretical probability only applies to dice.
Experimental probability is based on actual trail results while theoretical probability is based on fixed value.
