Question 1194127
Given a set A = {7,5,6,H,G,n}, answer the following questions:

recall that: The subsets of any set consists of all possible sets including its elements and the null set. Let us understand with the help of an example.

Example: Find all the subsets of set A = {1,2,3,4}

Solution: Given, A = {1,2,3,4}

Subsets =

{}

{1}, {2}, {3}, {4},

{1,2}, {1,3}, {1,4}, {2,3},{2,4}, {3,4},

{1,2,3}, {2,3,4}, {1,3,4}, {1,2,4}

{1,2,3,4}


so, in your case

a. Find the number of subsets of A

∅ | {5} | {6} | {7} | {G} | {H} | {n} | {5, 6} | {5, 7} | {5, G} | {5, H} | {5, n} | {6, 7} | {6, G} | {6, H} | {6, n} | {7, G} | {7, H} | {7, n} | {G, H} | {G, n} | {H, n} | {5, 6, 7} | {5, 6, G} | {5, 6, H} | {5, 6, n} | {5, 7, G} | {5, 7, H} | {5, 7, n} | {5, G, H} | {5, G, n} | {5, H, n} | {6, 7, G} | {6, 7, H} | {6, 7, n} | {6, G, H} | {6, G, n} | {6, H, n} | {7, G, H} | {7, G, n} | ...
