A company has a total of 300 machines the probability of any
A company has a total of 300 machines. the probability of any one machine not working is.003. what is the probability that one or more is not working
Solution
probability that machine is not working is 0.003
therefore the probability that machine is working will be 1 - 0.003 = 0.997
we have to find the probability that one or more machine not working = 1 - probability all machine are working
probability all machine are working = 300C300*(0.997)^300*(0.003)^0 =0.4060
THEREFORE ANSWER IS 1 - 0.4060 = 0.5940
