How many rows in the truth table of a 2-input OR gate produce output 0?
Explanation
For a 2-input OR gate only one row (A=0 B=0) produces output 0. All other combinations produce output 1.
Reference: Computer Studies Textbook , Page 3
Hint
OR gives 0 only when every input is 0 — how many ways can that happen with 2 inputs?
