If A={1,2,3} and B={4,5}, then A×B= ___.
{(1,2),(1,3),(2,3),(4,5)}
{(4,1),(4,2),(4,3),(5,1),(5,2),(5,3)}
{(1,4),(1,5),(2,4),(2,5),(3,4),(3,5)}
{(1,4),(1,5),(2,4),(2,5)}
The Cartesian product of sets A and B is defined as: A×B={(a,b):a∈A,b∈B} ⇒A×B={(1,4),(1,5),(2,4),(2,5),(3,4),(3,5)}
If set A = {1, 2, 3}, set B = {4, 5}, then find A × B.
