Question

4.A ={ 1,3.4,7,8} which of the following is not a subset of set A​

Answer 1

Step-by-step explanation:

The empty set {} is a subset of {1,2,3,4,5}=1

And these are subsets: {1}, {2}, {3}, {4} and {5} =5

And these are also subsets: {1,2}, {1,3}, {1,4}, {1,5},{2,3}, {2,4}, {2,5} , {3,4}, {3,5}, {4,5}=10

And these are also subsets:{1,2,3}, {1,2,4}, {1,2,5}, {1,3,4}, {1,3,5}, {1,4,5}, {2,3,4}, {2,3,5}, {2,4,5}, {3,4,5}=10

And these are also subsets:{1,2,3,4}, {1,2,3,5}, {1,2,4,5}, {1,3,4,5}, {2,3,4,5}=5

And {1,2,3,4,5} is a subset of {1,2,3,4,5}=1

Total=1+5+10+10+5+1=32

If the original set has n members, then the Power Set will have 2^n members

here n is 5

so 2^5=32.

So 32 Subsets are There in {1,2,3,4,5}
