Consider an ideal quantum gas of Fermi particles at a
temperature T,
a) Write the probability p(n) that there are n
particles in a state of one particle given as a function of the
average occupation number, <n>.
b) Find the root of the fluctuation to the average square in the
occupation number of a single-particle state as a function of the
occupation number
average <n>. Sketch the result
