Example 14: If A Bwrite A B A B in simplest form.
Properties of Intersection and Union Operations:
• Idempotent Law: For all A A A ...
A A ...
• Commutative Property: For all A and B A B .........
A B ........
• Associative Property: For all A ,B and C A B C ....A B C...
A B C ...A B C...
• Identity Element A ...
A ...
• The Distributive Law for intersection operation over union operation:
A ∩(B∪C) = (A…B)∪ (A…C)
• The Distributive Law for union operation over intersection operation:
A ∪ (B ∩C) = (A....B) ∩ (A...C)
