A union is often thought of as a marriage.

Math union of sets examples. Scroll down the page for more examples. Our mother always keeps the kitchen well arranged. We use and for intersection and or for union. Commutative associative identity and distributive.

Sets intersection union and complement. For example the union of three sets a b and c contains all elements of a all elements of b and all elements of c and nothing else. The union of two sets x and y is equal to the set of elements which are present in set x in set y or in both the sets x and y. We next illustrate with examples.

Let a and b be two finite sets such that n a 20 n b 28 and n a b 36 find n a b. Let s look at some more examples of the union of two sets. We will now focus on the associative properties for set union and set intersection. Find the union of a and b.

The intersection of two sets is the set of elements which are in both sets. Solved basic word problems on sets. Draw and label a venn diagram to show the union of p and q. Now the union of a and b written a b 1 2 3 4 5.

Basically we find a b by putting all the elements of a and b together. The union and intersection of a family of sets. 7 daily life examples of sets. The phrase does not imply that the union set is a finite set.

It is denoted by a b and is read a union b. This operation can be represented as. A b pronounced as a intersection b are members that are common to both set a and set b. The union of two sets is the set of elements which are in either set.

A finite union is the union of a finite number of sets. Thus x is an element of a b c if and only if x is in at least one of a b and c. The following table gives some properties of union of sets. The plates are kept separate from.

A b 1 2 3 4 5 now let us learn how can we represent the union of two sets in a venn diagram. In section 5 3 we discussed various properties of set operations. Let a 1 2 3 and b 3 4 5. Notice that the definition of set union tells us how to form the union of two sets.

Let a 1 2 3 and let b 3 4 5. A x or a y let us consider an example say. Universe 1 2 3 4 5 6 7 8 9 10 a 2 4 6 8 10 b 6 7 8 9 10 show step by step solutions. Word problems on sets are solved here to get the basic ideas how to use the properties of union and intersection of sets.

Let counting numbers p multiples of 3 less than 20 and q even numbers less than 20. A b pronounced as a union b are members that are in set a or set b or both. Kitchen is the most relevant example of sets. Let a 1 orange 1 pineapple 1 banana 1 apple and b 1 spoon 1 knife 1 fork a b 1 orange 1 pineapple 1 banana 1 apple 1 spoon 1 knife 1 fork example 2.

Given u 1 2 3 4 5 6 7 8 10 x 1 2 6 7 and y 1 3 4 5 8. Union of sets definition.
