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′).
An empty set is represented as:
{0}.
{}.
{∅}.
0.
Given that sets: P = {1, 2, 3, 4, 5} and Q = {2, 5}.
The relationship between the sets P and Q is:
P ⊂ Q.
P ∪ Q = Q.
P ∩ Q = ∅.
Q ⊂ P.
Given that Q is a set and that n(P(Q)) = 64, where P(Q) is the power set of Q, n(Q) = :
4.
8.
6.
5.
Given that P and Q are disjoint sets. The relationship between P and Q in set notation is:
P = Q.
P ∪ Q = ∅.
P ∩ Q = (∅).
n(P ∩ Q) = 0.
