Assume that a = 3, b = 2, and c = 1. What is the value of each of the following Boolean expressions?

Assume that a = 3, b = 2, and c = 1. What is the value of each of the following Boolean expressions? Show your work.

1.  (a > 1) OR (b = c)
2. ((a + b) > c) AND (b < c)
3.  NOT (a = 1)
4. NOT ((a = b) OR (b = c)).
5. (a = 1) AND (b = 1) AND (c = 2)
6.  (a = 1) OR (b = 1) OR (c = 2)

Part 2 

Assume that a = 4, b = 3, and c = 2. What problem do you encounter when attempting to evaluate this Boolean expression? Give a couple examples illustrating the problem.

(a = 2) OR (b = 3) AND (c = 4)

How can this problem be solved?
