haphazardness are irrelevant. The fields of mathematics, probability, and statistics use formal definitions of randomness. In statistics, a random variable is an assignment of a numerical value to each possible outcome of an event space. This association facilitates the identification and the calculation of probabilities of the events. A random process is a sequence of random variables describing a process whose outcomes do not follow a deterministic pattern, but follow an evolution described by probability

The days to repair component was calculated by using the probability distribution of repair times 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. TIME BETWEEN BREAKDOWNS The time between breakdowns

INFERENCE We often need to know something about a large population. Eg: What is the average number of hours per week devoted to online social networking for all US residents? It’s often infeasible to examine the entire population. Instead, choose a small random sample and use the methods of statistical inference to draw conclusions about the population. But how can any small sample be completely representative? We can’t act as if statistics based on small samples are exactly representative of the entire

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.

Copies Case Problem Assignment #1 MAT540, Strayer University Assignment#1: JET Copies Case Problem According to the discrete distrubution, the number of days (y) needed to repair the copier is as follows (where “R2” is a random value in the excel sheet between and 0 and 1): 0 < R2 < .2, then it takes 1 day .2 < R2 < .65, then it takes 2 days .65 < R2 < .9, then it takes 3 days .9 < R2 < 1, then it takes 4 days James estimated that the time between break-downs
