questions. a. Use the multiplication rule to find the probability that the first two guesses are wrong and the third and fourth guesses are correct. That is‚ find P(WWCC)‚ where C denotes a correct answer and W denotes a wrong answer. b. Make a complete list of the different possible arrangements of 2 wrong answers and 2 correct answers‚ then find the probability for each entry in the list. c. Based on the preceding results‚ what is the probability of getting exactly 2 correct answers when 4 guesses

The contingency tables and relative frequency probabilities in this exercise are based on the Springdale Shopping Survey database. Information like that gained from the two parts of this exercise could provide helpful insights into the nature of the respondents‚ their perceptions‚ and their spending behaviors. In particular‚ part 2 examines how conditional probabilities related to spending behavior might vary‚ depending on the gender of the respondent. Based on the relative frequencies for responses

Learning Outcomes of the Course On completion of the module‚ students should be able to ILO1. distinguish between population and sample; apply the different sampling techniques to select a sample; ILO2. compute central tendency measures as the arithmetic mean‚ median and mode; ILO3. compute dispersion measures as the range‚ interquartile range‚ standard deviation and variance; ILO4. define probability of a simple event; correctly use the

Probability sampling Probability sampling is a type of sampling that includes random selection. And in order to achieve random selection‚ it must be made sure that different units of population have equal probability of being chosen. Some relevant terms: N = the number of cases in the sampling frame n = the number of cases in the sample f = n/N = the sampling fraction I] Simple Random Sampling It is the simplest type of probability sampling‚ wherein the probability of an element

can define a problem‚ specify the probability of certain events‚ identify alternative solutions‚ and state the probability of each solution leading to the desired result. Like in the case of construction‚ the construction cost overrun risk has a possibility that during the design and construction phase‚ the actual project costs will exceed projected costs as a result of weather‚ supplier’s shortage‚ labour and subcontractor performance. In this case the probability that this will happen will be dependent

TABLE OF CONTENTS CONCEPTS OF RISK AND UNCERTAINTY 1 Definition Economic Risk Economic risk is the chance of loss because all possible outcomes and their associated probabilities are unknown.Actions taken in such a decision environment are purely speculative‚ such as the buy and sell decisions made by speculators in commodity‚ futures and option markets. All decision makers are equally likely to profit as well as to lose‚ luck is the sole determinant of success or failure. 2 Definition of

bag of M&M’s? Purpose of Project / Aim: Probability is an educated thought or guess to determine if a particular event will occur. Probability is important to assist in making and predicting everyday decisions; the probability that a child will be born with sickle cell disease or the probability that crops will die are all important for the human survival. The use of M&M’s is to substitute for the examples listed above to examine probability considering they are used in everyday life and
