Give a combinatorial proof that the cardinality of the power set of a finite set A is 2^|A|
juin [17]

There are \dbinom{|A|}k ways of building a subset of k elements from A, so the total number of subsets you can build is

\displaystyle\sum_{k=0}^{|A|}\binom{|A|}k

Recalling the binomial theorem, the above sum is equal to

\displaystyle\sum_{k=0}^{|A|}\binom{|A|}k1^k1^{|A|-k}=(1+1)^{|A|}=2^{|A|}

as required.
