Answer:

11. AnB or intersection of sets

AnB = {a, h}

12. A' means yung mga wala sa circle A

A' = {p, m, d, r, f, g, z}

13. AnB'

A= w,c, b, t, a, h

B'= p, w, c, b, t, m, z}

AnB' = {w, c, b, t}

14. (AuB)' yung wala sa circle A& B

(AuB)' = {p, m, z}

15. (AnB)' lahat maliban sa intersection

(AnB)' = {p, w, c, b, t, m, d, r, f, g, z}
