Answer (2)
Explanation:
Case 1: If A = 0 and B = 0 are both true, the LED will light up. If Y = 1 is true, the LED will light up.
Case 2: A = 0 and B = 1.
LED Y = 0 will not have any current flowing through it.
Case No. 3: A = 1 and B = 0
No current will flow through LED Y = 0 once more.
Case 4: A = 1, B = 1, and Y = 0 once more.
