Define exclusive events.

Hint: In order to solve this problem, we need to understand the definition of exclusive events. Exclusive events are events which cannot occur at the same time. That means the occurrence of one event makes another event almost impossible.

Complete step by step answer:
Let’s first understand by exclusive events.
Exclusive events are also called mutually exclusive events.
Exclusive events are events which cannot occur at the same time.
Let's understand by taking an example of a company who has a budget of 50 lacs.
And the projects available project a that is of 40 lacs and project B that is of 15 lacs.
Therefore, we cannot sign two projects at a time either one event is performed or the second.
Therefore, event A and event B are exclusive events.
We can also understand it better by taking an example of rolling a die.
When a random die is thrown there is no chance that two events will occur simultaneously.
Therefore, these two events are exclusive events.

Note: It is easy to confuse between independent events and exclusive events. We cannot mix exclusive events with independent events. Independent events have no impact on the viability of other options. In the example of rolling a die, the event of getting a number and getting a number once again with another throw has no relation in them. Thus, these events are independent events, while the events where we get two numbers at one roll is impossible. So, these events are exclusive events.
