Consider a situation where cars entering an intersection each could turn right, turn left, or go straight. An experiment consists of observing two vehicles moving through the intersection.(a) How many sample points are there in the sample space?List the events in the sample space. (Enter your answer in set notation. Use G for go straight, L for left, and R for right.)S =(b) Assuming that all sample points are equally likely, what is the probability that at least one car turns left? (Enter your probability as a fraction.)(c) Again assuming equally likely sample points, what is the probability that at most one vehicle turns? (Enter your probability as a fraction.)

A survey was being conducted to learn about attitude of a certain population towards the medical and housingplans. The survey asked the male and female respondents that how important the level of risk they had felt inchoosing a housing or a medical plan. The following table was constructed from the data provided. “High”means the respondent said level of risk was either important or very important. Male FemaleHigh 22 27Low 28 23 3 (b) List some possible events from the above random experiment. 3 (c) What is the probability of a survey respondent had said that the level of risk isHigh? Write the sample space of this random experiment. Suppose if a female respondent is selected randomly, what is the probability thisfemale respondent had said level of risk is High?

We randomly select a batch of 40 computer disks for shipment. The probability of selecting a good disk is the same as the probability of selecting a defective disk. In part C, you will determine the probability that this shipment contains 10 defective disks and 30 good disks for our batch or 15 defective disks and 25 good disks for our batch. Note: I am not asking for an example of an outcome, although I may ask for examples of outcomes on the exam. A. What is the size of your sample space S? i.e., How many different outcomes (batches of 40 disks) in your sample space? What are the conditions? What counting technique(s) are you using? B. How many outcomes when randomly selecting 10 defective disks and 30 good disks for our batch or 15 defective disks and 25 good disks for our batch. What are the conditions?

A variable y of a finite population has the frequency distribution shown in the table. Suppose a member is selected at random from the population and let Y denote the value of the variable y for the member obtained. Complete parts (a) through (d) below. y 3 4 6. f 1 1 11 7 a. Determine the probability distribution of the random variable Y. 3 y P(Y = y) (Type integers or decimals. Do not round.) b. Use random-variable notation to describe the events that Y takes on the value 5, a value less than 5, and a value of at least 5. The event that Y takes on the value 5 can be represented as The event that Y takes on a value less than 5 can be represented as The event that Y takes on a value of at least 5 can be represented as { }. c.
