formula of n anb What is the Formula for the Cardinality of A union B The cardinality number of elements of A union B can be calculated by counting the elements in A and B and taking the elements that are common only once The formula for the cardinality of A union B is n A U B n A n B
The set formula is given in general as n A B n A n B n A B where A and B are two sets and n A B shows the number of elements present in either A or B and n A B shows the number of elements present in both A and B We apply P A B formula to calculate the probability of two independent events A and B occurring together It is given as P A B P A P B where P A is Probability of an event A and P B Probability of an event B

The union of two sets A and B denoted A B is the set that combines all the elements in A and B In symbols x U x A B x A x B The set difference between two sets A and B denoted by A B is the set of elements that can only be found in A but not in B N AuBuC n A n B n C n AnB n BnC n AnC n AnBnC Explanation Let us come to know about the following terms in details n AuB Total number of elements related to any of the two events A B n AuBuC Total number of elements related to any of the three events A B C n A Total number of elements related to A
The union operation i e A B is one of the important operations in sets This article explores the A B formula the number of elements in A B formula A B formula in probability and the complement of the A union B formula Below we formally provide the formula and then explain the intuition behind it If A and B are two events in a sample space S then the conditional probability of A given B is defined as P A B frac P A cap B P B textrm when P B 0

A union B formula In sets U stands for the term union and A U B means any element in set A or set B Hence an A U B set will contain all the elements present in both A and B It can simply be found by putting all the elements of set A and set B together and removing all the common duplicate elements N A B 0 and hence n A B n A n B Formula 1 Now apply this to a set and its complement to get n A0 n Ac n U n A where U is the universal set Formula 2 The shaded region below is A Bc and A Bc A B so n A Bc n A n A B
The mathematical study of randomness is called the theory of probability probability model has two essential pieces of its description S the sample space the set of possible outcomes An event is a collection of outcomes A fs1 s2 sng and a subset of the sample space N n r times nr Example in the lock above there are 10 numbers to choose from 0 1 2 3 4 5 6 7 8 9 and we choose 3 of them 10 10 3 times 103 1 000 permutations So the formula is simply nr
