Consider firstly their definition: Where $Q_{i}$ is the value of a dichotomous observable measured at time $t_{i}$, and the joint probabilities are obtained repeating the experiment. Postulate 1 provides that Q(t) is a well defined quantity for every time t, even for times different from $t_{i}$ and $t_{j}$. Thus it is possible to define a three-time probability and to obtain $P_{ij}(Q_{i},Q_{j})$ as its marginal, for notation simplicity set $i=1$ and $j=2$. Where the subscript $12$ specifies

(a) If a student is chosen randomly, what is the probability that he or she is not in any of these classes? (b) If a student is chosen randomly, what is the probability that he or she is taking exactly one language class? (c) If 2 students are chosen randomly without replacement, what is the probability that at least one is taking a language class? 4. A CEO wants to decide how much to invest on a project. If the firm invest x, then the probability of success is 1 − e−2x . If the project succeeds,

diagram was made, the cumulative profit for each possible outcomes were estimated, and the expected value analysis based on the selling probability estimated by Warren was also computed. All other factors involved that may affect the outcome of a sale is not considered. Only the condition set forth by the client as well as the estimated selling costs and selling probabilities were considered. This analysis, while in the third person is from the point of view of Mr. Warren, the owner of Warren Agency, Inc

With regards to the days to repair component, it was calculated by using the probability distribution of repair times that was given. This was used along with a set of random numbers based on 100 breakdowns a year. Then, a vlookup was used and the probability distribution per day to come up with the days to repair, which varies based on the random number that excel generates. The random number represents the probability of how many days it would take to repair the copier. Interval between breakdowns

For my task, I was asked a series of questions that required deep statistical analysis of the information provided and discovered. I was given a copy of date from the SAT Score Roster sent to the high school by the College Board. This roster showed gender, verbal and math scores of 303 students in a recent graduating class. With that information I took a random sample of 30 by number 1 to 303 on my list and generating 30 random integers with my calculator. I did not include repeats. I used that sample

CHAPTER 9 RISK AND RETURN FOCUS Our initial focus is on defining risk in financial terms and understanding how that concept fits into portfolio theory. As we gain a more sophisticated understanding of risk, we're able to focus on the concept of beta and how to apply it through the SML. PEDAGOGY The study of Risk and Return presents the biggest pedagogical challenge in basic finance. Therefore motivating the study and developing ideas patiently is especially important.
