Question

18. The Boolean expression (not p) + pq +q has value = 0 when
Op = 0 and q = 1
Op= 1 and q = 0
Op = 1 and q = 1
Op = 0 and q = 0

Expert Solution

Step 1

not operation:
not p is 1 when p is 0
not p is 0 when p is 1

and opertion:
pq is 1 when both p and q are 1, otherwise it is 0

or operation
p+q is 0 when both p and q are 0, other wise it is 1

Step by step
