Machines in a factory break down according to a Poisson process with X = 5 breakdowns per week. Let X be the number of breakdowns in the first week, and let Y be the number of breakdowns in the first three weeks. Derive the conditional probability mass function of X given Y = 20: p(x|Y = 20).This should reduce to a distribution you know well!
