Vedclass · Answer

(C) The number of elements in set $A$ is $n = 5$. The total number of subsets of a set with $n$ elements is given by the formula $2^n$. Here,the total number of subsets is $2^5 = 32$. $A$ proper subset is any subset of $A$ except the set $A$ itself. Therefore,the number of proper subsets is $2^n - 1$. Substituting the value of $n$,we get $2^5 - 1 = 32 - 1 = 31$.

If $A = \{ 1, 2, 3, 4, 5 \}$,then what is the number of proper subsets of $A$?
