Question 450996: copyqwik has four photocopy machines a,b,c,d. the probability that a given machine will break down on a particular day is p(a)=1/50 p(b)= 1/60 p(c)= 1/75 p(d)= 1/50. Assuming independance what is the probability on a particular day that all 4 machines will break down? and none will break down? Answer by jorel1380(3719) (Show Source):
You can put this solution on YOUR website! Probability that all 4 are broken down:1/50x1/60x1/75x1/50=1/11250000.
-------------
Probability that none will break down=49/50x59/60x74/75x49/50=10482766/11250000..
