Correct. There are $\displaystyle{4}\cdot{8}={32}\usepackage{cmbright}\Huge\$ ways to get a King and either a Queen or a Jack and there are $\displaystyle\frac{{{52}}}{{{502}}}={1326}\usepackage{cmbright}\Huge\$ two-card combinations, so the probability of getting a King and either a Queen or a Jack is $\displaystyle\frac{{32}}{{1326}}=\frac{{16}}{{663}}\usepackage{cmbright}\Huge\$ .
