Among 81678167 cases of heart pacemaker malfunctions, 457457 were found to be caused by firmware, which is software programmed into the device. if the firmware is tested in 33 different pacemakers randomly selected from this batch of 81678167 and the entire batch is accepted if there are no failures, what is the probability that the firmware in the entire batch will be accepted? is this procedure likely to result in the entire batch being

Ответ:
Part a)
Total number of cases = 8167
Number of Malfunctions due to firmware = 457
Probability that a malfunction is because of firmware =
Probability that the malfunction is not because of firmware = 1 - Probability that a malfunction is because of firmware =
Probability of selecting 3 pacemakers without a malfunction because of firmware =
Part b)
The probability of selecting 3 pacemakers without any malfunction because of firmware is 0.841, which is a high probability. So we can say, yes this procedure is very likely to result in entire batch being accepted. The probability near 1 is considered a very higher probability for an event and the probability near 0 is considered a very lower probability for an event.
