Question

How do you calculate theoretical probability?

Answer 1

Answer:

Step-by-step explanation:

In theoretical probability we are relying on the nature of the experiment and the event and not the actual conducting of the experiment. So what we are getting from calculating a theoretical probability is simply an expectation as to what can happen and to what extent can it happen.

Let the outcomes associated with an experiment be represented in a set S

called the sample space.

Then n(S)

gives the number of total outcomes.

Let the favorable outcomes of the event be represented in set A. Then n (A) given the number of favorable outcomes of the event.

Then before calculating the theoretical probability it is a must check that all outcomes of the experiment has an equal chance of occurrence. Only then we proceed to calculation. If the outcomes are not equally likely to occur then we do not calculate the theoretical probability.

When the chances are equally likely then the theoretical probability is given by:

n(A)/n(S)
