Question

find the proper subset of W={5, 6,7}​

Answer 1

Answer:

Subsets of a set can be formed by choosing no elements to one or more elements from the set.

If a set contains ‘n’ elements, then the number of proper subsets of the set is

${2}^{n} - 1$

If A={p,q} the proper subsets of A are [{},{p},{q}]

Number of proper subsets of A are

${2}^{3} - 1 = 8 - 1 = 7$

Hence, all the Subsets of A=ϕ,{5},{6},{7},{5,6},{6,7},{7,8},{5,6,7}

Answer 2

Answer:

{5},{6},{7},{5,6},{5,7},{6,7},{5,6,7},{}
