The experimental probability is the occurrence probability of an event concerning all events. The experimental probability of pizza or steak is P(P or B) = 35%
What is the experimental probability?
The experimental probability is a probability assigned to an event. It is the number of times an event occurs concerning the number of times all events occur or the experiment is repeated.
It can be calculated by taking the relative frequency of the event when the experiment is repeated several times.
To calculate it, we can use the following formula,
P(E) = Number of trials performed in which a certain event occurred / Total number of trials in which all events occurred
In the exposed example,
- The type of food are the events ⇒ pizzas, hamburgers, pastas, and
steaks.
- The number of times each event is repeated is 8, 12, 14, 6 respectively
- Total number of trials in which all events occurred ⇒ 8+12+14+6
- The events of interest are pizza or steak
- The number of times pizza or steak occur is 8 and 6 respectively
- Number of trials performed in which these events occurred ⇒ 8+14
P(E) = Number of trials performed in which a certain event occurred / Total number of trials in which all events occurred
P(P or B) = (8 + 6) / (8 + 12 + 14 + 6) = 14 / 40 = 0.35 = 35%
The experimental probability of pizza or steak is P(P or B) = 35%
