You are a quality control manager in a chainsaw manufacturer company, producing chainsaws in 4 different sizes in three factories. Each day, Factory 1 produces 21 small and 21 medium chainsaws; Factory 2 produces 21 medium and 21 large chainsaws; and Factory 3 produces 14 medium, 14 large and 14 extra large chainsaws. Assuming that you select 6 products randomly for quality control purposes, what is the probability that you will find 6 large chainsaws, at least 5 of which are produced in the second factory?
