Question

define Union and intersection in short way right now​

Answer 1

union of sets means combining 2 sets and writing all the elements of both sets in a single set.

For example,

A = { 1,2,3}

B = { 4,5,6 }

(A U B) = { 1,2,3,4,5,6}

Intersection of sets means writing the common elements of 2 sets in a single set.

For example,

X = { 1,2,3,4}

Y = { 4,5,6,7}

(X Π Y) = { 4 }
