Question

Find all subsets of the set (2,4,11)

Answer 1

A set of "n" distinct elements has 2ⁿ subsets.

So, you will have 2³ = 8 subsets.

 

(2, 4, 11)

(2)

(4)

(11)

(2,4)

(2,11)

(4,11)

∅, the empty is a subset of every set.

 

Answer 2

{2}, {4}, {11}

 

{2, 4}, {2, 11}, {4, 11}

 

{2, 4, 11}

 

{} (null set)
