In one town, the number of burglaries in a week has a Poisson distribution with mean μ = 3.5. Let variable x denote the number of burglaries in this town in a randomly selected month. Find the smallest usual value for x. Round your answer to three decimal places. (HINT: Assume a month to be exactly 4 weeks)
