(and typically is not allowed to switch lines). Multiple-Server Waiting Line Model The formulas for M/M/S are applicable if the following conditions exist: The arrivals follow a Poisson probability distribution. The service time for each server follows an exponential probability distribution. The service rate µ is the same for each server. The arrivals wait in a single waiting line and then move to the first open server for service. Multiple-Server Waiting Line Model

40% of those in default were made to high-risk borrowers. What is the probability that a high-risk borrower will default? 2. A fund manager is considering investing in the stock of a healthcare provider. The manager’s assessment of probabilities of the rates of return on this stock over the next year is summarized in the table below. Rate of return Less than -10% -10% to 0% 0% to 10% 10% to 20% More than 20% Probability 0.04 0.14 0.28 0.33 0.21 Let A be the event “Rate of return will be more

26 35 43 Chapter 1 Some Basic Concepts 1.1 Probability It is customary to begin courses in statistics with a discussion of probability and then go on to derive certain propositions in probability theory. The problem with this approach is that probability is a difficult and potentially confusing subject. The foundations of probability theory are not well established. There are at least three different ways of thinking about probability. (a) (b) (c) Relative Frequency Subjective

Probability.1.The probability of an event is a numerical measure of the chance or likelihood that the event will occur. 2.A probability is always measured on a scale of 0 to 1. Methods of assigning probabilities: Classical Method：Assigning probabilities based on the assumption of equally likely outcomes. Relative Frequency Method：Assigning probabilities based on experimentation or historical data. Subjective Method：Assigning probabilities based on judgment Definitions 1.Outcome (or elementary event)

What is the probability of randomly obtaining a score between 300 and 600 on the GMAT exam? Solution The following sketch depicts the problem graphically: determine the area between x = 300 and x = 600, which spans the mean value. Because areas in the z distribution are given in relation to the mean, this problem must be worked as two separate problems and the results combined. A z score is determined for each x value. and Note that this z value (z = -1.94) is negative. A negative z value

See worksheet "Decision Tree" 3 Detailed description of Real Option Technique "First, using a decision tree, I came up with a simple expected value of $13,980,000 based on the costs to complete each phase, the probabilities of completing each phase, and the costs and probabilities associated with failure at each step in the approval process. The expected value of successful completion with Depression only was $36,390,000, for weight only $1,200,000 and for both $26,880,000. The expected value

yellow balls. Two balls are drawn from the urn at random, without replacement. (a) In this scenario, what is the experiment? What is the sample space? (b) What is the probability that the first ball drawn is red? (c) What is the probability that at least one of the two balls drawn is red? (d) What is the (conditional) probability that the second ball drawn is red, given that the first ball drawn is red? Solution. (a) The experiment is the drawing of two balls from the urn without replacement.
