Let S={1,2,3,4,.............10}. A subset B of S is said to be good if the product of the elements of B is odd, Then the probability that a randomly chosen subset of S is good is

Let S={1,2,......,20} .A subset B of S is said to be nice ,if the sum of the elements of B is 204 . Then the probability that a randomly chosen subset of S is nice is (k)/(2^(18)) , where k is.

Let S={1,2,...,20}. A subset B of S is said to be 'nice', if the sum of the elements of B is 203. Then the probability that a randomly chosen subset of S is 'nice' is: (a) 7/(2^20) (b) 5/(2^20) (c) 4/(2^20) (d) 6/(2^20)

Let S={1,2,3,.....50} The number of non empty subsets A of S such that the product of elements is A is even

Let S={1,2,3,......,100}. The number of non-empty subsets A of S such that the product of elements in A is even is

Let S={1,2,3, …, 100} . The number of non-empty subsets A to S such that the product of elements in A is even is

Set S has 4 elements A and B are subsets of S. The probability that A and B are not disjoint is

let S = {2,4,6.............20), what is the number of subsets does S have?

Let X={2,3,4,5,6,7,8,9,10} .A subset S of X is said to be good if it has exactly four numbers and their g.c.d is 1 .Then ,the number of good subsets of S is
