Let p₁ be the probability that the subject used 2 addictive substances, p2 the probability that the subject used fewer than 4 addictive substances, p3 the probability that the subject used more than 6 addictive substances, and p4 the probability that the subject used between 5 and 8 addictive substances, inclusive. Then the P₁, P2, P3, and P4 are, respectively, (Choose one from the following which is closest to the correct answer.) O a. 0.1817, 0.8857, 0.0168, 0.0277.
