statistical mechanics - From Fermi-Dirac to Maxwell-Boltzmann statistics

I have a little question I can't seem to find the answer to. It is as follows:

When does Fermi-Dirac statistics reduce to Maxwell-Boltzmann statistics?

Answer

The Fermi-Dirac distribution

$$ f = \frac{1}{1+e^{(E-\mu)/kT}} $$

where, $E$ is the energy, $\mu$ is the chemical potential and $kT$ is Boltzmann's constant times temperature reduces to the Boltzmann distribution

if $E \gg \mu$ then $e^{(E-\mu)/kT} \gg 1$ and so you can write $$ f \approx e^{-(E-\mu)/kT}. $$
