Answer:

a) tie the exception condition to a processing step

Explanation:

Numbering exception conditions, in a fully developed use case description is helpful to tie the exception condition to a processing step

The fully developed use case description is useful for the documentation of the context, purpose, description, conditions, and workflow of each use case.

X = 1 if (A = 1 OR B = 1) OR (A = 0 AND B = 1
Gnoma [55]

Answer:

For question a, it simplifies.  If you re-express it in boolean algebra, you get:

(a + b) + (!a + b)

= a + !a + b

= b

So you can simplify that circuit to just:

x = 1 if b = 1

(edit: or rather, x = b)

For question b, let's try it:

(!a!b)(!b + c)

= !a!b + !a!bc

= !a!b(1 + c)

= !a!b

So that one can be simplified to

a = 0 and b = 0

I have no good means of drawing them here, but hopefully the simplification helped!
