Example of Rational Numbers
// probability one is 1 in 8 rational p1 (1,8);
// probability two is 2 in 3 rational p2 (2, 3);
// probably of both together is their product rational p3 = p1 * p2;
// probably of either independent is their sum rational p4 = p1 + p2;
// what is this probability? cout << "combined probability is " << p3 << endl; cout << "independent probability is " << p4 << endl
