Empty set is a subset of every set. $\{\phi\}\subseteq 2^S $. I feel this is also trivial property since $\phi \in 2^S$ is trivial property as power set will always contain null set. For eg, if $2\in A$ then $\{2\}\subseteq A$. $\{\phi\}\in P(A)$ is not trivial though as for that $\phi \in A$ must be true Is this correct? @Shaik Masthan @Lakshman Patel RJIT 0 votes 0 votes Lakshman Bhaiya commented Nov 27, 2018 reply Follow Share Yes,it seems right 0 votes 0 votes Please log in or register to add a comment.
