Boolean Algebra

Which expression is equivalent to $A'B + AB$?

Simplify: $A(A + B)$

How many ordered pairs $(A, B)$ make $A' + B$ true? ($A$ and $B$ are each 0 or 1)

Simplify: $A + A'B$

Simplify: $(A + B)(A + B')$

Which law states that $A + AB = A$?

What is $(A + B)'$ simplified using DeMorgan's?

Simplify: $A'B'C + A'BC + AB'C + ABC$

Find all ordered triples $(A, B, C)$ where $A$, $B$, $C$ are each 0 or 1 that make $A'BC + AB'C$ true. List them as comma-separated triples.

How many ordered pairs $(A, B)$ make $A'B + AB'$ true? ($A$ and $B$ are each 0 or 1)

Simplify: $(AB)'$ using DeMorgan's Law.

Simplify: $AB + AB' + A'B$
