Question

In Boolean algebra, $A+B=Y$ implies that

• A. sum of $A$ and $B$ is $Y$.
• B. $Y$ exists when $A$ exists or $B$ exists or both $A$ and $B$ exist.
• C. $Y$ exists only when $A$ and $B$ both exist.
• D. $Y$ exists when $A$ or $B$ exist but not when both $A$ and $B$ exist.

Answer 1

The correct option is B $Y$ exists when $A$ exists or $B$ exists or both $A$ and $B$ exist.

In Boolean algebra, $A+B=Y$ implies that $Y$ exists when $A$ exists or $B$ exists or both $A$ and $B$ exist.
