Question

In Boolean algebra A.B=Y implies that :
  1. product of A and B is Y
  2. Y exists when A exists or B exists
  3. Y exists when both A and B exist but not when only A or B exists
  4. Y exists when A or B exists but not both A and B exist.

A
product of A and B is Y
B
Y exists when A or B exists but not both A and B exist.
C
Y exists when A exists or B exists
D
Y exists when both A and B exist but not when only A or B exists
Solution
