Given the sets P = {1, 3, 5, 6} and
Q = {2, 4, 7, 8}, then n( P ∩ Q) is:
{0}.
{∅}.
∅.
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).
An empty set is represented as:
{}.
Given the set M = { prime factors of 25}, M is:
{5}.
{5, 25}.
{1, 5, 10, 25}.
{1, 5, 25).
Given that Q is a set and that n(P(Q)) = 64, where P(Q) is the power set of Q, n(Q) = :
