Question

Find the power set of X=(1,2,3,)

Answer 1

AnSwer:

Power set of a set is the number of possible sets of the given set.

★Our set:

• X = ( 1 , 2 , 3 )

So,

P(X) = { {} , {1} , {2} , {3} , {1,2} , {1,3} , {2,3} , {1,23} }

• Here {} = empty set

• Remember No. of elements in power set = 2ⁿ , where n = number of elements in intial set.
