11. Which of the following relationships represents the dual of the Boolean property x + x'y = x + y Choose the best answer.

- x'(x + y') = x'y'
- x(x'y) = xy
- x*x' + y = xy
- x'(xy') = x'y'
- x(x' + y) = xy

3 is WRONG. In this special case, the "+" has higher precedent than the "*" between the x and x', so you need to use parenthesis with the x'+ y term before ANDing it with the x.
