In this chapter we have discussed Probability, the most popular of the entire syllabus of Mathematics in IIT JEE and AIEEE preparation. PROBABILITY defines how probable an event may be. However, an event which is bound to occur, is called certainty. Probability is measured on a scale of 0 to 1.
In this chapter we shall study the methodologies of computing the probability of an event, be it complex or simple. We shall try to comprehend the tools used for this purpose. In an attempt to make the subject easily comprehensible and clearly understandable a large number of illustrations and problems are selected and solved. Every aspect is fully supported by sufficient number of relevant examples. The students will note that for the understanding of the subject matter of this chapter, the knowledge of permutation and combination (presented in the previous chapter) is essential.
The syllabus includes: Computation of probability of events using permutation and combination. Addition and multiplication rules of probability, conditional probability, independence of events.
The chapter starts with some basic definitions of Experiments, Sample Space and Event. This is followed by the types of events.
Topics Covered under Probability are:-
Probability is not an easy topic but a tricky one. Despite of this it is not difficult to score in the questions based on this topic. It is important from the perspective of all engineering examination including IIT JEE and AIEEE. IIT JEE and AIEEE definitely have 2-3 questions every year directly on these topics. It is very important to master these concepts as this becomes quite crucial in outperforming others in Competitive examination.
