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?

A manufacturing company produces 10,000 products a day. From
previous experience, quality control analysts estimate that 0.5% of
products manufactured have some kind of defect and cannot be sold.
The defective products are thrown away and treated as a loss. It
costs $1.00 to manufacture, distribute, and market each individual
unit, regardless of whether or not the product has a defect. The
unit retail price is $5.00, and each of the non-defective products
sells with probability 0.95.
