PROBABLITY 2A. Suppose that there is a prize ceremony awarding prizes to 10 finalists. Each finalist is going to get exactly one prize, but assume that each has an equal probability of receiving any given prize. The grand prize is $5000, there are 2 prizes of $2000, 2 prizes of $1000 and 5 prizes of $200. Let X represent the amount of money won by one prize recipient. Find E(X), var(X) and σ for X. 2B. A pair of dice...

Consider an urn with 4 balls: one ball is worth 4, two balls are worth 10 each, and one ball is worth 14. Suppose you randomly draw two balls from the urn at the same time Let random variable X denote the sum of the values of these two balls. Calculate the variance of X. Round your answer to the third decimal place (e.g. for 3.141592..., enter 3.142) Answer:

Two individuals, A and B, are finalists for a chess championship. They will play a sequence of games, each of which can result in a win for A, a win for B, or a draw. Suppose that the outcomes of successive games are independent, with P(A wins game) = 0.3, P(B wins game) = 0.2, and P(draw) = 0.5. Each time a player wins a game, he earns 1 point and his opponent earns no points. The...

2019/Midterm At Unknown University, the Admissions department has discovered that the best applicants usually go to bigname schools instead and the worst often do poorly in courses, so the school wants to concentrate recruitment efforts and financial aid resources on the middle half of the applicants. You must write a c++ program that takes a file containing a list of applicants, in which each applicant has a total SAT score, and prints a list of the middle half of these...

Question 3 Frenzy ltd. desires to locate a new facility. Based on preliminary analysis, the choice has been reduced to four locations: A, B, C, and D. These four locations were rated on a scale from 1 (worst) to 10 (best) on each of four criteria. Each criterion was also weighted to indicate its importance (i.e., the higher the weight, the more important).The list of ratings and weights follows in the Table 3 below: Table 3 Factors Score Evaluation by...
