This IIT-JEE maths examination video is based on the topic probability. This topic is also interesting and you will enjoy while solving problems based on probability. It is simple because you will not have to remember many formulas in this maths video lecture. Also, you should have thorough knowledge of permutation and combinations for understanding probability better.
Students need to understand the various principles of probability to solve the problem easily. If you understand this topic well then there you can easily score good marks in probability. Many a times student do not get good tutorials for understanding this topic and they end up getting confused. But this video lecture has simplified the understanding of the topic and will help you to solve the problems correctly. Many questions are asked in JEE examination and you will enjoy while watching these video lectures.
Random experiment is an experiment whose outcome cannot be predicted or cannot be said anything certainly. Example: Tossing affair coin. Now when we toss a coin, you may get a head or a tail, but you cannot predict the result. Example: Drawing a card from a well shuffled pack of cards. When we play cards, and take out a card from a well shuffled pack, then which card will come out is a random process. Example: Throwing an unbiased dice. When you throw a die, you don’t know what number you will get, it can be anything between one to six. Hence, any experiment the outcome of which cannot be predicted is called a random experiment in probability.
These video lectures on IIT JEE maths probability examination are based on several examples on probability which will help you understand the topic better.
Sample space: if you perform a trial, then a set in this experiment, say a set of all possible outcomes/ results of a random experiment are called a sample space. And each element of the sample space is called sample point. Example: If you toss a coin, then there are only two possible results. Sample space will be given by either head or tail. Hence sample space will contain two elements, head or tail = S {H, T}. Similarly, throwing a die, sample space will contain 6 digits because out of 6 digits you can have any outcome such as S = { 1,2,3,4,5,6}. Similarly, you will be able to understand several other concepts in this video lecture.
