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.
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 F = {football players} and G = {girls}, the set notation for the statement ‘All girls play football’ is:
G ⊂ F.
G ∩ F.
F ⊂ G.
G ∪ F.
The shaded region in the figure is represented as:
(A ∩ B)’.
A ∪ B.
A’ ∪ B’.
(A ∪ B)’.
Given the sets P = {1, 3, 5, 6} and
Q = {2, 4, 7, 8}, then n( P ∩ Q) is:
0.
{0}.
{∅}.
∅.
