IIT JEE Solved Problem Examples for Probability
IIT JEE Solved Problem Examples for Probability includes SOME DEFINITIONS : Elementary Events : If a random experiment is performed, then each of its outcomes is known as an elementary event. Sample Space : The set of all possible outcomes of a random experiment is called the sample space associated with it and it is generally denoted by S. e.g. Let there be a bag containing 3 white and 2 black balls. Let the white balls be denoted by W W W 1 2 3 , , and black balls be denoted by B B 1 2 , . If we draw two balls from the bag, then there are 5 2 C elementary events associated to this experiment. These elementary are : B W B W B W B W B W B W W W 1 1 1 2 1 3 2 1 2 2 2 3 1 2 , , , , , , , W W 1 3 , W W 2 3 , and B B 1 2 . The set of all these elementary events is the sample space associated to the experiment. Compound Event : A subset of the sample space associated to a random experiment is defined as compound event if it is disjoint union of single element subsets of the sample space.
