Question

If n(P)=5 and n(Q)=8. What is the greatest possible value of n(PnQ)?

Answer 1

The greatest possible value of n(P∩Q) can be 5.

• Given, n(P) = 5 and n(Q) = 8.
• Intersection of two sets is the set containing elements which are present in both the sets.
• The maximum number of possible elements which can be present in both the sets is 5.
• Therefore, the greatest possible value of n(P∩Q) = 5.
