What Is A Intersection B Union C?
A intersection B union C gives the elements which are in the set A and are common in both the sets, the set B and set C. The notation of A intersection B union C is A n ( B U C). Here A n ( B U C) can be computed in two simple steps. First, we need to find the union of B and C, which is B U C. Second we need to take the intersection of the set A and set B U C. Thus we can obtain A n ( B U C) in two simple steps.
The below Venn diagram shows A n ( B U C) which is the region in the set A and is common to both the sets B and set C. This A intersection B union C is identified with the shaded region in the middle of the venn diagram.
Here let us try to understand this with the help of a simple example. Let us take the set A = { 1, 2, 3, 4, 5}, B = }, B = {3, 4, 5, 6, 7}, C = {6, 7, 8, 9, 10}
B U C = {3, 4, 5, 6, 7, 8, 9, 10}
A n ( B U C) = {1, 2, 3, 4, 5} n {3, 4, 5, 6, 7, 8, 9, 10}
= {3, 4, 5}
Here we have used the basic definition that the intersection of two sets is obtained by taking the common elements and the union of two sets has been obtained by taking all the elements of the two sets. Thus we have obtained the result set A intersection B union C.
How To Find A Intersection B Union C?
The final answer of A intersection B union C can be computed from the following sequence of steps.
 First, we need to find the union of the elements of set B and set C. The is represented as B U C.
 Second, we need the intersection of the elements of set A and the resultant set B U C. This is represented as A n (B U C).
Here we have found A n ( B U C), which is the result of two simple steps of finding the union and then finding the intersection of the sets. This can be easily represented as A n B U C = A n (B U C).

Examples on A Intersection B Union C

Example 1: Find the set A intersection B union C, given that A = {1, 2, 3, 4, 5}, B = {4, 5, 6, 7}, and C = {3, 4, 5, 6, 7, 8, 9}.
Solution:
The given sets are as follows.
A = {1, 2, 3, 4, 5}, B = {4, 5, 6, 7}, and C = {3, 4, 5, 6, 7, 8, 9}
The aim is to find A intersection B union C.
A n B U C = A n ( B U C)
= {1, 2, 3, 4, 5} n ({4, 5, 6, 7} U {3, 4, 5, 6, 7, 8, 9})
= {1, 2, 3, 4, 5} n {3, 4, 5, 6, 7, 8, 9}
= {3, 4, 5}
Therefore, the set A intersection B union C is {3, 4, 5}.

Example 2: Find the set A intersection B union C, given that A = {4, 5}, B U C = { 2, 3, 4, 5, 6, 7}.
Solution:
The given sets are as follows.
A = {4, 5}, B U C = { 2, 3, 4, 5, 6, 7}.
The aim is to find A intersection B union C.
A n (B U C) = {4, 5} n { 2, 3, 4, 5, 6, 7}
= {4, 5}
Therefore, A n (B U C) is equal to {4, 5}.
