Question

which of the following is not a subset of the set T? T={1,2,3,5,7,9,11,13}

Answer 1

Step-by-step explanation:

B

C, D and E

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.

Answer 2

$\large{\underline{\underline{\bold{\red{\sf{Bonjour !}}}}}}$

subsets of T are

{1,2,3}

{2,5,7,11}

{13,11,2,3}

and many more
