How Does the Einstein Model Estimate Excited State Probability?

[nitefalls]

Homework Statement

In the Einstein model of a particular solid, one quantum of vibrational energy
is ΔE=0.050 eV. This means an energy equal to ΔE is needed to raise an oscillator from
one energy level to the next highest level. Assume this solid is at room temperature. What
is the probability that any particular oscillator will be found in its first excited state, relative
to the probability of finding it in its ground state?

How many atoms have a kinetic energy less than 0.05 eV? How many have a kinetic energy that's more than 0.05 eV but less than 0.10 eV? You can use the Maxwell-Boltzmann distribution to figure this out.
