July 16th problem

Good hard problem.

Couldn't you treat this as a simple binomial distribution.
n =7
p = Pr( of picking your own coat/hat) = 1/n = 1/7
E(X) = n x p = n x 1/n = 1.

Binomial distribution?

Each subsequent Bernoulli Trial is independent of the previous one in the binomial distribution. Here, if you pick a coat, that coat is no longer available for the next person to pick, so there is no independence.

This will show that the problem described here cannot be modeled with the binomial distribution.
