Answer 17

select the intersection of sets (i,n,s) and (f,i,k,,p, u)
which one is correct (u) (m) (i) (f,i,k,n,p,s,u)

Answer 18

intersection of sets basically mean elements that these sets BOTH have.

So we have {i, n, s} and {f, i, k, p, u}
What elements do both sets have?

Answer 19

(u) (m) (i) (f,i,k,n,p,s,u)

Answer 20

ok, do you know what element both sets have?

Answer 21

no

Answer 22

we have sets {i, n, s} and {f, i, k, p, u}

look at these elements from these sets. do you see what element both sets have?

Answer 23

they both have an i in the sets
