The dipole moment of a molecule can be predicted by looking at the molecule's structure and the location of the dipoles within the molecule. When a molecule has no dipole moment, it will be nonpolar. A molecule with a dipole moment will be polar.
The reason why polar molecules attract nonpolar molecules is just because in this case it is the dipole in the polar molecule that induces the dipole in the nonpolar molecule. The two opposite poles would then attract. This is the Debye force. It is true that Debye attraction is stronger that dispersion force, but the presence of polar molecules among nonpolar ones will not sort of 'override' the attraction between nonpolar molecules themselves.
