In Boolean expression A + B = Y implies that
Options
- AY exists when A or B exists but not when both A and B exist.
- BY exists only when A and B both exist.
- CY exists when both A and B do not exist.
- DY exists when A exists or B exists or both A and B exist
Correct answer
D. Y exists when A exists or B exists or both A and B exist
Step-by-step solution
The Boolean expression A + B = Y represents the logical OR operation. In an OR operation, the output Y is true (exists) if input A is true, or input B is true, or both inputs A and B are true. Thus, Y exists when A exists, or B exists, or both A and B exist. Answer: Y exists when A exists or B exists or both A and B exist
