Question
The need for a particular type of machine at oil well is
random event and independent....
The need for a particular type of machine at oil well is
random event and independent. It is known that the average need is
3 machines per week (3 machines/week). Generally, requesting and
purchasing new equipment and resources from the head office is
placed every Monday and arrived by the end of the week (Thursday
noon). If last Monday only one machine was available in the oil
well, so the manager requested 5 additional machines to be
delivered by end of the week. (a) What is the probability (%) that
10 machines will be needed next month? (b) What is the probability
(%) that only one machine will be available on Thursday morning
before the new equipment delivered. (c) What is the probability (%)
that obtaining at least one machine from the manager will not be
possible (currently occupied & unavailable) by Thursday
morning? (d) What is the probability (%) of at least 4 machines
will be available on next Monday
