A pharmaceutical company recently hired 4 biologists, 6 chemists, 5 environmental scientists, and 2 economists for various upcoming projects. Suppose that the company wants to form an interdisciplinary project group of 6 from these new hires to assess the potential environmental impact of developing a new experimental drug. Which of the following gives the total number of project teams that contain at least 2 environmental scientists? Question 4Answer a. P(5, 2)P(12, 4) b. C(5, 2)C(12,4) c. P(5, 2)P(12,4) + P (5, 3)P(12,3) + P(5, 4)P(12, 2) + P(5,5)P(12, 1) d. C(17,6)–(C(5,0)C(12,6) + C(5, 1)C (12,5)) Which of the following gives the probability that a randomly selected project team contains one biologist, two chemists, and no economists? Question 5Answer a 14+26+35+ 02 b. C(4, 1) + C(6, 2) + C(5, 3) + C(2, 0)C(17, 6) c. P(4, 1)P(6, 2)P(5, 3) P(17,6) d. C(4, 1)C(6, 2)C(5, 3)C(17,6)
