Thanks 😊

Answer 1

Yes they are the same. This is due to De Morgan's Law.

Answer 2

Y	Z	Y' + Z'	(YZ)'
0	0	(1 + 1) = 1	(0.0)' = (0)' = 1
0	1	(1 + 0) = 1	(0.1)' = (0)' = 1
1	0	(0 + 1) = 1	(1.0)' = (0)' = 1
1	1	(0 + 0) = 0	(1.1)' = (1)' = 0

The result is due to de Morgan's law, but you can confirm it for yourself using a truth table.
