Question

E={a,c,f}
A={a,c,j}

find the intersection of E and A.
find the union of E and A
write your answer using set notation (in roster form)​

Answer 1

Answer:

i. E ∩ A = { a , c }

ii. E ∪ A = { a , c , f , j }

Step-by-step explanation:

Given

E = { a , c , f }

A = { a , c , j }

i) Let's find the intersection of E and A

E ∩ A = { a , c , f } ∩ { a , c , j }

In the case of intersection , we have to list the elements which are common in both sets:

E ∩ A = { a , c }

ii) Let's find the union of E and A

E ∪ A = ( a , c , f } { a , c , j }

In the case of Union, we have to list all the elements which are present in both sets.

E ∪ A = { a , c , f , j }

Hope this helps..
