The correct option is C A∩B=B∩A
Given two sets: A={a:a is a prime number<25} &
B={b:b∈N,10≤b≤18}
Now, in roster form:
A={2,3,5,7,11,13,17,19,23} &
B={10,11,12,...,16,17,18}
Now, we know the commutative property of both union and intersection of sets.
⇒A∩B=B∩A & A∪B=B∪A
Also, A∩B={11,13,17}.
Also, this means A⊄B.
