Question

Which of these is a subset of A ={ 1,5,7,9 } *

1 point

{1,3}

{1,3,7,8}

{ }

{ 5,6,7 }

​

Answer 1

Answer:

Given U={1,3,5,7,9,11,13},A={0},B={2,4},C={1,9,5,13},

D={5,11,1},E={13,7,9,11,5,3,1},F={2,3,4,5}

Now we have to find the subsets of U

Consider A={0}

Since 0∈

/

U,A⊈U

Consider B={2,4}

Since 2,4∈

/

U,B⊈U

Consider C={1,9,5,13}

Since 1,9,5,13∈U,C⊂U

Consider D={5,11,1}

Since 5,11,1∈U,D⊂U

Consider E={13,7,9,11,5,3,1}

Since 13,7,9,11,5,3,1∈U,E⊆U

Consider F={2,3,4,5}

Since 2,3,4∈

/

U,F⊈U

Therefore C,D,E are subsets of U.
