## MCQ on probability

Agricultural statistics is an very important subject of B. Sc Agriculture. In M.Sc. Agricultural, the students of each faculty use it in their research work. Apart from all these, questions related to statistics are asked in various competitive exams. These questions also include multiple choice questions related to probability. In this post, we will solve the questions related to this topic.

### What is probability?

In statistics and mathematics, probability describes how an event can occur or what are the possibilities of its happening. In probability, value is expressed from 0 to 1.

### Why probability?

There is always a possibility of the occurrence of any event, although we cannot say with certainty that the event will happen. So we use this method for an approximate result. Where this rule is applicable, decisions can be taken with its help.
