Answer:
B. 2,3,4
Step-by-step explanation:
INTERSECTION OF SETS
The intersection of two sets A and B is the set composed of the common elements that belong to both A and B. It is denoted by A ( inverted U ) B, read as “A intersection of B.”
Example 7
a. If
P = {o, r, a, n, g, e} and
Q = {a, p, p, l, e}
then P ∩ Q = { a , e }
b. If
R = {4, 8, 16, 20} and
S = {4, 5, 9, 17}
then R ∩ S = { 4 }
c. If
T = {2, 4, 6, 8} and
U = {1, 3, 5, 7}
then R ∩ T = { } or an empty set
