```How do I use Mathematica to solve this problem?

I selected with replacement 100 times from a set of N objects. The
results:

1 item came up 4 times
1 item came up 3 times
10 items came up 2 times each
73 items came up 1 time each
the other N-85 items did not come up at all

Based on this histogram, what's the 1) most likely value of N, and 2)
the probability distribution of N?

Of course, I'm actually interested in the general solution: if I
select with replacement M times from a set of N objects, and get a
resulting histogram H, what's the probability distribution of N with
respect to M and H?
