Here again is the information about the prescription drug: There is a 20% chance of experiencing dizziness (D) and a 40% chance of experiencing a headache (H). The information also states that there is a 15% chance of experiencing both side effects. What is the probability of experiencing neither of the side effects? Q 0 85 O 0.60 O 0.55 O 0.48 O 0.40 The following probabilities are based on data collected from US. adults during the National Health Interview Survey 2005-2007. Individuals are placed into a smoking category based on whether they ever smoked 100 cigarettes (in their lifetime) and their behavior in the last 30 days. Never Former Current Non-daily Current Daily Probability 0.576 0.215 0.04 0.169 Based on these data, what is the probability that a randomly selected U.S. adult currently smokes? 0.209 0.169 0.04 0.0068 OOOOO none of these A family plans to have 3 children. For each birth, assume that the probability of a boy is the same as the probability of a girl. What is the probability that they will have exactly one girl? O 0.5 O 0.125 O 0.375 O 0.875 O none of theseFour students attempt to register online at the same time for an Introductory Statistics class that is full. Two are freshmen and two are sophomores. They are put on a wait list. Prior to the start ofthe semester, two enrolled students drop the course, so the professor randomly selects two of the four wait list students and gives them seats in the class. What is the probability that both students selected are freshmen? 1/12 1/6 1/4 1/2 00000 It is impossible to tell because the outcomes are not equally likely. The student, obviously, is interested in the probability that when the set time occurs, at least one of the four alarms will buzz. This probability is equal to: O (.02)4 O (.98)4 O 1 - (.02)4 O 1 - (.98) 4 O none of theseThe next three questions refer to the following information: According to the information that comes with a certain prescription drug, when taking this drug, there is a 20% chance of experiencing dizziness (D) and a 40% chance of experiencing headaches (H). The information also states that there is a 15% chance of experiencing both side effects. What is the probability of experiencing dizziness ora headache? 0.45 0.30 0.08 0000 A person at a carnival decides to toss rings until he hits the target, but he will not toss more than 3 times. Let H denote a hit and M denote a miss. What is the sample space for this random experiment? O S= {HHH, HHM, HMH, HMM, MHH, MHM, MMH, MMM} O S = {H, HH, HHH} O S = {H, HM, HHM, HHH} O S = {H, MH, MMH} O S = {H, MH, MMH, MMM}A person at a carnival tosses rings at a target exactly 3 times. Let H denote a hit and M denote a miss. Define the event A as "the person hits the target at least one time." What are the possible outcomes for this event? O {H, HH, HHH} O {H, MH, MMH} O {HHH, HHM, HMH, HMM, MHH, MHM, MMH} O {HHH, HHM, HMH, HMM, MHH, MHM, MMH, MMM} O {HMM, MHM, MMH}A fair die is rolled 12 times. Consider the following three possible outcomes: (i) 526321416534 (ii) 1 12 2 3 3 4 4 5 5 6 6 (iii) 6 66666666666 Which of the following is true? O (i) is more likely than (ii) or (iii). O (ii) is more likely than (iii). The three outcomes are equally likely. O It is absolutely impossible to get sequence (iii). Both (A) and (B) are true.Again, only 20% of the students in a certain liberal arts college are males. If two students from this college are selected at random, what is the probability that they are of the same gender? O 0.04 O 0.16 O 0.64 O 0.32 O 0.68Let A and B be two disjoint events such that P(A) = .20 and P(B) = .60. What is P(A and B)? O 0 O 0.12 0.68 O 0.80 O none of the aboveIn a large population, 8% of the males have had a kidney stone. Suppose a medical researcher randomly selects two males. Let X represent the event the first male has had a kidney stone. Let Y represent the event the second male has had a kidney stone. Which of the following is true about the two events? X and Y are disjoint. X and Y are independent. Both (A) and (B) are true. 0000 None of the above are true. The next two questions refer to the following information: Only 20% of the students in a certain liberal arts college are males. Question 10 of 11 Iftwo students from this college are selected at random, what is the probability that they are both males? 0.04 0.40 0.36 00000 0.25 The next two questions refer to the following information: A particular student has a lot of trouble getting up in the morning. To make sure he will not oversleep, he sets four identical alarm clocks. Each of the four alarms will buzz at the set time with a probability of .98 independently of the others. What is the probability that when the set time arrives, all four alarms will buzz? 0 4*(.98) * (.02)3 0 4*(.02) * (.98)3 O (.02)4 O (.98) * 4 O (.98)4Here again is the information about the prescription drug: There is a 20% chance of experiencing dizziness (D) and a 40% chance of experiencing headaches (H). The information also states that there is a 15% chance of experiencing both side effects. What is the probability of experiencing only dizziness? O 0.35 O 0.20 O 0.12 O 0.05 O none of these
