Question

how do I find all the possible subsets of a set (a, b, c, d) ?

Answer 1

{a}, {b}, {c}, {d},{a,b},{a,c},{a,d},{b,c},{b,d},{c,d},{a,b,c},{a,c,d},{b,c,d}{a,b,c,d}, {}
this is how I think.....you have to look for all possible combinations which can be made from the given set(super-set) .

Answer 2

the correct answer is 32 for this problem... how do I find that?

Answer 3

Oh, the number of subsets is 2^n. Where n is the number of elements. In this case you get 2^4=16. It shouldn't be 32.

Answer 4

oh, you're right. Thank you!

Answer 5

No problem :P
