Ex.1. On an average Friday‚ a waitress gets no tip from 5 customers. Find the probability that she will get no tip from 7 customers this Friday. The waitress averages 5 customers that leave no tip on Fridays: λ = 5. Random Variable : The number of customers that leave her no tip this Friday. We are interested in P(X = 7). Ex. 2 During a typical football game‚ a coach can expect 3.2 injuries. Find the probability that the team will have at most 1 injury in this game. A coach can expect 3.2 injuries

Probability 1 0.05 2 0.10 3 0.30 4 0.30 5 0.20 6 0.05 1.00 a. Simulate the emergency calls for 3 days (note that this will require a “running”‚ or cumulative‚ hourly clock)‚ using the random number table. b. Compute the average time between calls and compare this value with the expected value of the time between calls from the probability distribution. Why are

include probabilistic cash flows‚ risk adjusted discount rates and the idea of real options. PEDAGOGY We begin with the idea that cash flows are random variables‚ which implies that project NPVs and IRRs are also random variables with associated probability distributions. We then explore the implications of choosing a high risk project over one with less variability‚ and conclude that managements would often trade higher return for lower risk if they had the necessary information. With that background

Ch. 7 The Normal Probability Distribution 7.1 Properties of the Normal Distribution 1 Use the uniform probability distribution. MULTIPLE CHOICE. Choose the one alternative that best completes the statement or answers the question. Provide an appropriate response. 1) High temperatures in a certain city for the month of August follow a uniform distribution over the interval 64°F to 92°F. What is the probability that a randomly selected August day has a high temperature that exceeded 69°F? A) 0.8214

provides a rational framework for choosing between alternative courses of action when the consequences resulting from this choice are imperfectly known. Two streams of thought serve as the foundations: utility theory and the inductive use of probability theory. The intent of this paper is to provide a tutorial introduction to this increasingly important area of systems science. The foundations are developed on an axiomatic basis‚ and a simple example‚ the "anniversary problem‚" is used to illustrate

Question 1 A Credit Default Swap (CDS) is an instrument designed to transfer the credit exposure of fixed income products between parties. A CDS is also referred to as a credit derivative contract‚ where the purchaser of the swap makes payments up until the maturity date of a contract. Payments are made to the seller of the swap. In return‚ the seller agrees to pay off a third party debt if this party defaults on the loan. A CDS is considered insurance against non-payment. A buyer of a CDS might

Convolution codes and viterbi algorithm Name Rahul Kumar Department of Electronics & Communication Engineering Lovely Professional University‚ Kapurthala‚ Punjab. Abstract:- A convolutional code is a type of error-correcting code in which each m-bit information symbol (each m-bit string) to be encoded is transformed into an n-bit symbol‚ where m/n is the code rate (n ≥ m) and the transformation is a function of the last k information symbols‚ where k is the constraint length of the code.
