The Cartesian product of finite and nonempty sets can be illustrated by the intersections of a crossing-line pattern, as shown to the right. {f, g, h} x {x, y} (a) Explain why the number of intersection points in the crossing-line pattern for AxB is ab, where a = n(A) and b = n(B). (b) Draw the crossing-line pattern for {A}{ (a) Each of the lines coming from set A intersects each of the lines coming from set B (b) Choose the correct answer below. A. {A} { B. . D. {A}>{ {A} { {A} { The Cartesian product of finite and nonempty sets can be illustrated by the intersections of a crossing-line pattern, as shown to the right. {f, g, h} x {x, y} (a) Explain why the number of intersection points in the crossing-line pattern for AxB is ab, where a = n(A) and b = n(B).
