How many different subsets of the set {0, 1, 2, 3, 4, 5,6,} do not contain 0?	Choose the correct answer
A) A.66	B) B.57	C) C.31	D) D.32	E) E.58
Number of subset   Since we have 6 digits other than 0, we can take any numbers from the set of 6 to make a subset. Also it is a matter of selection and not arrangement.So we will consider combinations.   6c1+6c2+6c3+6c4+6c5+6c6=57   And one set is the NULL set having no elements in it so    57+1=
