Question

Probability based upon knowledge of the situation is known as probability.

• A. Experimental
• B. Theoretical
• C. Unpredictable

Answer 1

The correct option is B Theoretical

Probability based upon knowledge of the situation is known as Theoretical Probability.

For example, if a coin is tossed 20 times, it is recorded that heads occurred 12 times and tails occurred 8 times.
In this case, the experimental probability of a head or a tail showing up would be:

P(Heads) $=\frac{12}{20}=\frac{3}{5}$

P(Tails) $=\frac{8}{20}=\frac{2}{5}$

whereas, the theoretical probability of a head or a tail showing up would be:

P(Heads) $=\frac{1}{2}$

P(Tails) $=\frac{1}{2}$
