List the elements in the set U qrstuvwxyz Aqsuwy Bqsyz Cvwxy

List the elements in the set:

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

A\' (upside down U) B\'

Solution

All elements are: U :q,r,s,t,u,v,w,x,y,z

A\' = r,t,v,x,z

B\' = r,t,u,v,w,x

A\' intersection B\' gives r,t,v,x
