You purchase a brand new car for $15,000 and insure it. The policy pays 78% of the car's value if there is an issue with the engine or 30% of the car's value if there is an issue with the speaker system. The probability of an issue with the engine is 0.009, and the probability there is an issue with the speaker system is 0.02. The premium for the policy is p. Let X be the insurance company's net gain from this policy. (a) Create a probability distribution for X, using p to represent the premium on the policy. Enter the possible values of X in ascending order from left to right. P(X) (b) Compute the minimum amount the insurance company will charge for this policy. Round your answer to the nearest cent

Which of the following is a false statement? O If two events are dependent, the probability of one event effects the probability of the other If two events are dependent, they cannot occur together. OIf two events are independent, the probability of one event has no effect on the probability of the other. If one event is dependent on another, then the second event depends directly on the outcome of the first event. acer F12 Sa Lk Pause Break PriSc F10 F11 F7 F8 F9 F5 420 & %
Consider the experiment: You ask someone two multiple-choice questions. Each question could be answered with Yes (Y), No (N), or Don't Know (D). (For example, if you ask someone these two questions, they could answer Yes to both of them, or Yes to the first one and Don't Know to the second one, etc.) Let A be the event that the person answers Yes to at least one question, and Let B be the event that the person answers No to the second question. How many elements are in the sample space? What elements are in A ∩ B? What elements are in A ′?

The probability value (p-value) for a hypothesis test represents a the probability the researcher made an error. b the probability of obtaining the data when HA is true. c the probability that the researcher made a correct decision. d the probability of obtaining the data when H0 is true.
ESP Experiment. A person has agreed to participate in an extrasensory perception (ESP) experiment. He is asked to randomly pick two numbers between 1 and 6. The second number must be different from the first. Let H= event the first number picked is a 3, and K= event the second number picked exceeds 4. Determine a. P(H). b. P(K| H). c. P(H&K). Find the probability that both numbers picked are d. less than 3. e. greater than 3.
On Mr. Casper's debate team at Thunderbird High School, 20% of the members are Sophomores, 35% are Juniors and 45% are Seniors. A team member is selected randomly to give the closing argument for the team. If a sophomore gives the closing argument, the team has a probability of 0.25 of winning the debate. If a junior gives the closing argument, the probability of winning is 0.6. If a senior closes, the probability of winning is 0.85. (a) Find the probability that the team wins the debate. b sketch a tree diagram to model this process
Assume that we have three coins: The first coin is fair. The second coin is unfair with probability of heads equal to 0.8. The third coin is also unfair with probability of heads equal to 0.3. Consider an experiment involving two successive coin tosses. The result of the first stage of the experiment is determined by the toss of the fair coin. The result of the second stage of the experiment is determined by the toss of a coin, but suppose that the coin that is used depends upon the result of the toss of the fair coin. Specifically, if the toss of the fair coin results in heads, then the second coin is tossed. Otherwise the third coin is tossed. Let Hi and Ti be the events that ith toss resulted in heads and tails, respectively. Answer the following questions. a) Give a sequential description of the experiment using a tree diagram. b) Calculate the probabilities of the possible outcomes of the experiment. c) Calculate P(H2) d) Are the events H1 and H2 independent?

Let A and B be two events such that the probability of B is 0.5 and the probability of both is 0.2. Find the probability of A given that B occurs.
Assume that we have three coins: The first coin is fair. The second coin is unfair with probability of heads equal to 0.8. The third coin is also unfair with probability of heads equal to 0.3. Consider an experiment involving two successive coin tosses. The result of the first stage of the experiment is determined by the toss of the fair coin. The result of the second stage of the experiment is determined by the toss of a coin, but suppose that the coin that is used depends upon the result of the toss of the fair coin. Specifically, if the toss of the fair coin results in heads, then the second coin is tossed. Otherwise the third coin is tossed. Let H, and T, be the events that ith toss resulted in heads and tails, respectively. Answer the following questions. Calculate P(H,). Are the events H, and H, independent? Justify your answer analytically.
