Set is the collection of the elements. We can perform much operation on the sets like union, intersection, difference and many more. So here we are going to discuss the intersection operation. Intersection means a set that is made by combining common elements of two or more sets. Intersection symbol is ∩. Suppose we have two sets P and Q then we can represent them as P∩Q. Let define the P and Q sets by an example.
Set P contain elements such as 1, 2, 3, 4, 5, 6, 7, 8, 9, 10,
Set Q contain elements such as 3, 5, 7, 8, 9, 12, 19, 23
So the intersection elements will be 3, 5, 7, 8, 9, it is because 3, 5, 7, 8, 9 elements are same in both of the sets
We can represent the all scenario by making a figure.
The shaded area of figure is showing intersections elements as we discussed above.
Let’s take another example to understand the intersection
Example: - Suppose we have two sets A and B
Set A = 2, 4, 5, 7, 8, 9, 12, 16, 19, 21, 23
Set B = 1, 3, 6, 9, 19, 21, 23, 29, 30
Than the intersection will be represented as A∩B = 9, 19, 21, 23
We can find the intersection for more than two sets just we have to take those numbers that are common in all three sets. Suppose we have A, B and C three sets than they can be represented as A∩B∩C.
At the time of dealing with central tendency one question is arises in everyone mind that how to find the mean, mean is the average of given distribution. Tamilnadu state board syllabus is very strong so due to this it has first rank among all boards.
