- Suppose a shipment of 130 electronic components contains 4 defective components. To determine whether the shipment should be accepted, a quality-control engineer randomly selects 4 of the components and tests them. If 1 or more of the components is defective, the shipment is rejected. What is the probability that the shipment is rejected?A certain group of women has a 0.210.21% rate of red/green color blindness. If a woman is randomly selected, what is the probability that she does not have red/green color blindness?
