Question

Determine the cardinality of the power set of the set {2,3,x,y,z}

Answer 1

Let us determine the cardinality of the power set of the set $\{2,3,x,y,z\}.$ Taking into account that the cardinality of the power set of the $n$-element set is equal to $2^n,$ we conclude that the cardinality of the power set of the set $\{2,3,x,y,z\}$ is equal to $2^5=32.$
