To follow up:

a) \(\displaystyle 12\in A\)

We see that 12 in deed listed as an element of set \(A\), so this is true.

b) \(\displaystyle 14\not\in B\)

We see that 14 is not given as an element of set \(B\), so this is true.

c) \(\displaystyle 14\not\in B\)

We see that 13 is given as an element of set \(B\), so this is false.

d) \(\displaystyle \{10,16\}\subset A\)

We see that both 10 and 16 are elements of set \(A\) and that set \(A\) has elements other than these two, and so this is true.

e) \(\displaystyle A\not\subset B\)

We see that there are elements in set \(A\) that are not in set \(B\), and so this is true.

f) \(\displaystyle B\subset A\)

We see that all elements of set \(B\) are also in set \(A\) and that there are elements in set \(A\) that are not in set \(B\) and so this is true.
