Among 8834 heart pacemokers, 504 were found to be defective. If five (5) pacemakers are selected, what is the probability that ot least one is defective? Remember 3 signilicant figures for probability. Using the same sample of pacemakers, where among 8834 heart pacemokers, 504 were found to be defective, what is the probability of selecting three defective pacemakers without replacement? Remember 3 signiticant figures for probability.
