operations. According to her assistant there are three options which merit consideration: A, B, and C. Moreover, there are three possible future conditions that must be included in the analysis: I, which has a probability of occurrence of .5; II, which has a probability of .3; and III, which has a probability of .2. If condition I materializes, A will cost $12,000, B will cost $20,000, and C will cost $16,000. If condition II materializes, the costs will be $15,000 for A, $18,000 for B, and $14,000 for C

Birthday Bound. In cryptography, birthday attack is a generic attack that exploits no specific properties within cryptographic schemes, but just takes the advantage of birthday paradox in probability theory. This paradox says, approximately 2n/2 independently random n-bit points will collide with a probability close-to-1, where 2n/2 is called the birthday bound [28,20]. The birthday attack itself is not fatal to the practical security of cryptographic schemes, because people can choose long-enough

large sums of money in developing an investment portfolio are risk averse. • This means investors expect a positive relationship between expected return and expected risk. Definition of Risk • Risk is the uncertainty of future outcomes. • Probability of an adverse outcome. Markowitz Portfolio Theory • Developed by Harry Markowitz in the 1950s. • Won a Nobel Prize for his work. • Basic portfolio model derived the expected rate of return for a portfolio of assets and an expected risk measure

with high quality processes. Introduction. The use of the standard Shewhart control chart for the fraction of nonconforming parts will produce a type I error–signaling that the process is out of control when, in fact, it is still in control–with probability 0 = 0.0027. When dealing with a process with both high quality and a large yield, the control limits for the Shewhart p-chart based on the normal distribution will become tighter, leaving a greater chance of a false alarm signal occurring. This
