b and c please

sharply 14. Consider a large two-state paramagnet with no external field. The multiplicity peaked at No = (a) Use Stirling's approximation to estimate the height of the peak. (b) Approximate the peak as a narrow rectangle containing all of the states. How wide is the peak? (c) What is the fractional width of the peak for N = 1020? (Hint: How many macrostates are there for this paramagnet?)
