Question

Dados A = {a, b, c, d} e B = {1, 2, 3}, o produto cartesiano A x B, terá 12 pares ordenados e será dado por:

AxB={(a, b),(a, c),(a, d),(b,a),(b,c),(b,d),(c,a),(c,b),(c,d),(d,a),(d,b),(d,c) }


A x B={(a,1),(a,2),(a,3),(b,1),(b,2),(b,3),(c,1),(c,2),(c,3),(d,1),(d,2),(d,3) }


A x B={(a,1),(a,1),(a,1),(b,2),(b,2),(b,2),(c,3),(c,3),(c,3),(d,4),(d,4),(d,4)}


A x B={(a,3),(a,2),(a, 5),(b,3),(b,2),(b,1),(c,3),(c,2),(c,1),(d,3),(d,2),(d,1) }
