Answer 2

Answer:

Which of the following is NOT a subset of set Q?

Q = {2, 3, 5, 7, 11}

(a) B = {3, 5, 2, 7}

(b) C = {2, 3, 7, 9}

(c) D = {7, 2, 3, 11}

d) All of the above.

Solution:

Know that, A is a subset of B: if every element of A is contained in B. This is denoted by $\[A \subset B\]$.

Observe that in C = {2, 3, 7, 9} is not a subset of Q because element 9 in not an element of Q.

Hence, the correct answer is option (b). i.e.  C = {2, 3, 7, 9}.
