Correct answer: C (parsed from the explanation — this source omits an answer key for this item)
Explanation
29 100 Choice C is correct. It’s given that out of every beads that the machine produces have a defect. It follows that if the machine produces k beads, then the 29 number of beads that have a defect is 100k, for some constant k. If a bead produced by the machine will be selected at random, the probability of selecting a 29 bead that has a defect is given by the number of beads with a defect, 100k, divided by the number of beads produced by the machine, k. Therefore, the 29 100k 29 probability of selecting a bead that has a defect is , or 100. k Choice A is incorrect and may result from conceptual or computational errors. Choice B is incorrect and may result from conceptual or computational errors. Choice D is incorrect and may result from conceptual or computational errors.
