In set notation, the number of elements in P and not in Q is:
n(P′ ∩ Q).
n(P ∩ Q′).
n(P′ ∪ Q).
n(P ∩ Q).
Inset notation, the shaded region in the figure is:
P' ∩ Q.
P ∩ Q'.
P ∩ Q.
Q' ∪ P.
The number of subsets of the set T = {a, b , c} is:
9.
3.
8.
6.
Given that sets: P = {1, 2, 3, 4, 5} and Q = {2, 5}.
The relationship between the sets P and Q is:
P ∩ Q = ∅.
Q ⊂ P.
P ∪ Q = Q.
P ⊂ Q.
Given the sets P = {1, 3, 5, 6} and
Q = {2, 4, 7, 8}, then n( P ∩ Q) is:
0.
∅.
{∅}.
{0}.
