    7 Basic Probability Problems

    See the attached file. 1. A certain coin has the same probability of landing heads as it does landing tails - but this coin is special, because it also has a 30% chance of landing on its side. a. What is the probability of this coin landing heads? b. What are the odds against this coin landing on its side? c. If this coin is

    Probability Distribution from a Given Data Set

    How you would use the concept of probabilities to apply to profiles for hiring more satisfied individuals? Job Satisfaction is an attitude about one's job. It may be measured globally or via facets (e.g., intrinsic / extrinsic). However, job satisfaction is a post hoc phenomenon. Using "profiles" developed via the DataSet to pre

    Monte Carlo Simulation Discussion

    Suppose we have a "black box" which on command can generate the value of a gamma random variable with parameters 1.5 and 1. Explain how we can use this black box to approximate E[exp(x)/(x+1)], where x is an exponential random variable with mean 1. I think it can be solved by importance sampling.

    Analyzing Poisson Distribution

    I would be grateful for an explanation to the following problem. Given that X possesses a Poisson distribution with mean u, show that the moment generating function of X is given by M(z)=exp(ue^z - u).

    Statistics question: Probability problems

    1. An investor owns three common stocks. Each stock, independent of the other, has equally likely chances of: (1) increasing in value, (2) decreasing in value, (3) remaining the same value List the possible outcomes of this experiment. Estimate the probability at least two of the stocks increase in value.

    Basic Statistics

    1. When two balanced dice are rolled, 36 equally likely outcomes are possible. Let X denote the smaller of the two numbers. If both dice come up with the same number, then X equals that common value. Find the probability distribution of X. Leave your probability in fraction form. a. x P(X=x) 1 5/18 2 2/9 3 1/6 4 1/9 5 1/18

    Binomial distribution in business applications

    The binomial distribution is regularly used in business applications. Why do you think this is the case? Can you give me two examples from a professional environment. Can you define binomial distribution?

    The use of z-scores to determine probability

    The instructions are typed exactly, word for word, from the text book. I am just as confused as you are, if not more. I wish I could give you more info, but that is all I have. The book is poorly written. The book has not covered Test Statistics yet, therefore that is not needed. The three chapters leading up to this assign
