Question

Find the union of the given pairs of set: A={a, e, i, o, u}, B={1, 2, 3}

Answer 1

concept : if two sets A and B are given, then union of set A and B is written as $A\cup B$. This is the set of all distinct elements that are in Both A or B. see figure, Venn diagram shown, represents that the $\cup$ of any two sets will give all the members of the two sets together, and not replicating the common member twice.

given, set A = {a, e , i, o, u } and set B = {1, 2, 3}
All the members of both sets together are; a, e, i, o, u, 1, 2, 3
here there is no one element is common in both sets.
so, A union B or $A\cup B$ = {a, e, i, o, u, 1, 2, 3}

Answer 2

Answer:

A U B = { a , e , i , o , u , 1 , 2 , 3 }

Step-by-step explanation:

Given A = { a , e , i , o , u }

B = { 1 , 2 , 3 }

A U B = { x : x € A or x € B }

= { a , e , i , o , u } U { 1 , 2, 3 }

= { a, e,i , o , u , 1 , 2 , 3 }
