When $E-\mu\gg k_BT$, either quantum occupation law reduces to the classical factor
$$
e^{-(E-\mu)/(k_BT)}.
$$

For a classical ideal gas the associated velocity distribution is $f(\mathbf v)=(m/(2\pi k_BT))^{3/2}\exp[-m|\mathbf v|^2/(2k_BT)]$. The occupation factor is the corresponding <Boltzmann distribution> for a one-particle energy.
