a$)$ Find the complement of the expression F $=$ x$$y$$z$+$ xy$$z$+$ x$$y$$z using Boolean algebra.

$(2$ pts$)$

b$)$ Simplify the complement to its simplest form using Boolean algebra and represent the

result in sum$-$of$-$product form. $(10$ pts$)$

First simplification, then complementing is NOT allowed.
