Question

U = {r,s,t,u,v,w,x,y,z}

Answer 1

Answer:

{r,z}

Step-by-step explanation:

U = {r,s,t,u,v,w,x,y,z}

P = {s,t,u,v,w}

Q = {u,v,x,y}

P' means elements in the universe,U, that are not in P.

P'={r,x,y,z}.

Q' means elements in the universe,U, that are not in Q.

Q'={r,s,t,w,z}.

P' intersect Q' means what elements are in common in both lists.

{r,z}
