# CBSE Class 11-science Answered

I am confused in a question from SETS AND RELATIONS P(A:B)={X:X∈P(A),B⊂X} In the given statement, does P(A:B) mean power set of ratio of set A and B? Please correct me if I am going wrong because I am not sure about it.

P(A:B) is the notation for the set which has all subsets of A which contain B.
So, if you take P(X:Y), it will contain all subsets of X which contain Y.
Yo can read it as power set of A is to B
