Each year the London Metropolitan Police record around 160 murders, and this has been stable for the last 5 years. Each of these murders is an individual crime that cannot be predicted. It may appear strange, but this very randomness means that the overall pattern of murders is in some ways quite predictable. Assuming the number of murders are Poisson distributed, compute the probability of having no murder during a day, 3 or more murders in one day, a week without any murder
