Give detailed Conception of : Power Sets

A Power Set is a set of all the subsets of a set.
Give detailed Conception of : subsets of a set.
Example: in the {a,b,c} example above, there are three members (a,b and c of course). So, the Power Set should have 23 = 8
mm detail
If we have a set {a,b,c}: Then a subset of it could be {a} or {b}, or {a,c}, and so on, And {a,b,c} is also a subset of {a,b,c} (yes, that's true, but its not a "proper subset") And the empty set {} is also a subset of {a,b,c}
In fact, if you list all the subsets of S={a,b,c} you will have the Power Set of {a,b,c}: P(S) = { {}, {a}, {b}, {c}, {a, b}, {a, c}, {b, c}, {a, b, c} } Think of it as all the different ways you can select the items (the order of the items doesn't matter), including selecting none, or all.
How Many Subsets Easy! If the original set has n members, then the Power Set will have 2n members
*2^n
voila
Thanks @nader1
n represents ?
*voila means ?? @nader1
i give you an example to understand of n Example: in the {a,b,c} example above, there are three members (a,b and c of course). So, the Power Set should have 23 = 8, which it doe
n is the number of objects in a set.. C = {2, 3, 4} Here, n = 3.. as there are three members ie 2, 3 and 4 in that set..
I got it thanks.
voila it is word a french here that come
I did not get you, what is the meaning of it?? Here we go??
like you give a final answer
I have read it somewhere in novel I think, but forget its meaning, Yeah Okay I get it..
