 Relative to this assignment, all of the following claims hold: whenever the value of \(x_1\) equals 7, the value of \(x_3\) equals 8; whenever the value of \(x_2\) equals 5, the value of \(x_3\) equals 8; whenever the value of \(x_1\) equals 7 and the value of \(x_2\) equals 5, the value of \(x_3\) equals 8; irrespective of the values of \(x_1\) and \(x_2\), the value of \(x_3\) equals 8. The question of dependence only becomes interesting and non-vacuous relative to a set of assignments:
