Expert Solution

Step 1

In probability theory, an event is an outcome or a set of outcomes of a random experiment to which a probability is assigned. A single outcome is an element of a sample space and different events in a random experiment are generally not equally likely, since they may include very different groups of outcomes.

There are various concepts of probability.

Simple probability : As mentioned above

Conditional probability : It is the probability of a certain event when the some other event had already occurred.

Sum of total probability : Finding unnational probability from all the conditional probabilities.
