Question

Consider the set A={1,2,3,4} . Find a proper subset B of A then find proper subset C of B. then find a proper subset D of C​

Answer 1

Answer:

Step-by-step explanation:

given :

• Consider the set A={1,2,3,4} . Find a proper subset B of A then find proper subset C of B. then find a proper subset D of C

to find :

• then find proper subset C of B. then find a proper subset D of C

solution :

• A = = {1, 2, {3,4}}

• Number of elements in A, n = 3.

• Total number of subsets of A = = 2¹ = 2³ =

• 8.

• Except for set A and null set, all other sets are proper sets.

• Hence number of proper subsets = 8 -

• 2 = 6
