define power set of a set |
|
Answer» The set of all the subsets of a set" Basically we collect all possible subsets of a set. Example: For the set {a,b,c}:• The empty set {} is a subset of {a,b,c}• And these are subsets: {a}, {b} and {c}• And these are subsets: {a,b}, {a,c} and {b,c}• And {a,b,c} is actually a subset of {a,b,c} too And altogether they make the Power Set: P(S) = { {}, {a}, {b}, {c}, {a,b}, {a,c}, {b,c}, {a,b,c} } |
