Question

solve this questions please of sets​

Answer 1

Step-by-step explanation:

(I) union sets .all elements that belongs to either A or B or both .ans= {0,1,2,3,4,5,6,7,8,9,11}.

(II) union sets = {0,1,2,3,4,5,6,7,8,10,20}.

(III) union sets = {0,3,5,7,9,10,11,20}.

(IV) intersections of sets . all elements belongs to both A and B. Ans = {3,5,7}.

(V) intersections of sets. ans= {0,5}.

(VI) intersections of sets. ans= {5,10)

And cardinal no of

(III)B and C =n(B and C) =8

(IV) A and B=n(A and B) =3

(V) A and C=n(A and C) =2

(VI)B and C =n (B and C) =2
