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)

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..

sinn is the total amount of students now and m were the students before, you subtract them both (n-m) and divide that by m. then, since to get a percentage from a fraction you have to multiply by 100, your answer should look like this: n-m/m*100
