Conditional Probability How to handle Dependent Events Life is full of random events! You need to get a "feel" for them to be a smart and successful person. Independent Events Events can be "Independent", meaning each event is not affected by any other events. Example: Tossing a coin. Each toss...
Bayes' theorem describes the relationships that exist within an array of simple and conditional probabilities. For example: Suppose there is a certain disease randomly found in one-half of one percent (.005) of the general population. A certain clinical blood test is 99 percent (.99) effective in detecting...

MAT 540 Quantitative Methods January 15, 2013 Six Sigma is a methodology developed to reduce defects in business processes, improve customer satisfaction and enhance the organization’s bottom line. Six Sigma reduces variation in production and business processes...
Probability 2 Theory Probability theory is the branch of mathematics concerned with probability, the analysis of random phenomena. (Feller, 1966) One object of probability theory is random variables. An individual coin toss would be considered to be a random variable. I predict if the coin...

PROBABILITY DISTRIBUTION In the world of statistics, we are introduced to the concept of probability. On page 146 of our text, it defines probability as "a value between zero and one, inclusive, describing the relative possibility (chance or likelihood) an event will occur" (Lind, 2012). When we think...

ABNORMAL RETURNS: A term used to describe the returns generated by a given security or portfolio over a period of time that is different from the expected rate of return. The expected...
PROBABILITY QUESTIONS Q1). You draw a card at random from a standard deck of 52 cards. Neither you nor anyone else looked at the card you picked. You keep it face down. Your friend then picks a card at random from a remaining 51 cards. a) What is the probability that your card is ace of spades...

Probability and Statistics, Spring 2009 Practice II Solutions Problem 1. Let X and Y be continuous independent random variables, Y is uniformly distributed in [0, 1] and X has an exponential distribution with a parameter λ = 1. Find P (X + Y ≥ 1). Solution: X has density fX (x) = e−x for x ≥ 0...
Probability The probability of an event occurring is the chance or likelihood of it occurring. The probability of an event A, written P(A), can be between zero and one, with P(A) = 1 indicating that the event will certainly happen and with P(A) = 0 indicating that event A will certainly not happen. ...

is said to have occurred. A probability is a way of assigning every event a value between zero and one, with the requirement that the event made up of all possible results (in our example, the event {1,2,3,4,5,6}) is assigned a value of one. To qualify as a probability, the assignment of values must...
