Question

let U={q,r,s,t,u,v,w,x,y,z}  A={q,s,u,w,y}  B={q,s,y,z         C=v,w,x,y,z determine the following A n B

nory · Answer

By A n B, do you mean A intersect B? Like the upside-down U?

anonymous · Answer

yes

directrix · Answer

(A ∩ B) = the set of elements in BOTH sets A and B.

{q,s,u,w,y} ∩  {q,s,y,z} = { q, 

q in both sets? Yes. The, q is a member of (A ∩ B).
-----

s in both sets A and B?
Yes, then s is a member of (A ∩ B) --> {q,s,u,w,y} ∩  {q,s,y,z} = { q, s, ?

Ask the same questions for elements u, w, and y.
Complete the intersection set.
