CAN SOMEONE PLSEASEEE HELP ME

Answer 1

4

Step-by-step explanation:

There are only 2 inputs, X and Y, and the number of different input configurations will be 2-to-the-power-of the number of inputs.

2² = 4

In other words, XY can be 00,01,10 or 11 and that's it. Four combinations.

BTW, (x AND Y) OR (NOT x AND NOT y) is allso called XNOR. See picture.
