A box in a supply room contains 24 compact fluorescent lightbulbs, of which 8 are rated 13-watt, 9 are rated 18-watt, and 7 are rated 23-watt. Suppose that three of these bulbs are randomlyselected. (Round your answers to three decimal places.)(a) What is the probability that exactly two of the selected bulbs are rated 23-watt?(b) What is the probability that all three of the bulbs have the same rating?(c) What is the probability that one bulb of each type is selected?(d) If bulbs are selected one by one until a 23-watt bulb is obtained, what is the probability that it is necessary to examine at least 6 bulbs?

Mr. Blackwells's class is conducting an experiment to find the probability of pulling certain colors from a bag of 25 marbles. If 2 are purple, 4 are yellow, 3 are green, and the rest are black, what is the probability of drawing a purple and yellow if the marbles are not replaced after they are picked?A. 1/150 B. 8/625 C. 2/75 D. 1/75
A study tracked a large group of people for 10 years. At the start of the study, 20% were heavy smokers (H), 30% were light smokers (L), and 50% were non-smokers (N). The interest of the study was whether the people in the study died during the study (D) or not die (Dc ). The probability that a light smoker died during the study was twice that of the probability of a non-smoker dying. Also, the probability that light smoker died during the study was half that of the probability of a heavy smoker dying. A randomly selected person from the study died during the study. What is the probability that this person was a heavy smoker (given they died, what is the probability they were a heavy smoker H)?
Suppose two friends, Michael and Austin, are arguing about Michael's supposed trivia prowess. Michael, a trivia fanatic, wishes to prove his vast trivia knowledge by answering a series of trivia questions. To test this, Austin purchases a book of trivia questions and randomly selects 75 to ask Michael. Assume that for each question, the probability that Michael gives the correct answer is 0.80. What is the probability that Michael will answer at least 55 questions correctly? Use the normal approximation to obtain the result. Give your answer as a decimal precise to at least three decimal places.
An hat contains 169 slips of paper. 27 of these are Blue; the rest are Pink. Two slips are selected at random from the hat. If the selection is made with replacement (the first slip is put back into the hat before drawing the second slip), the probability that both slips are Blue is
