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 = Q.
P ∩ Q = ∅.
Q ⊂ P.
P ⊂ Q.
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′).
Given the sets P = {1, 3, 5, 6} and
Q = {2, 4, 7, 8}, then n( P ∩ Q) is:
∅.
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.
