Chapter 2—Introduction to Probability PROBLEM 1. A market study taken at a local sporting goods store showed that of 20 people questioned‚ 6 owned tents‚ 10 owned sleeping bags‚ 8 owned camping stoves‚ 4 owned both tents and camping stoves‚ and 4 owned both sleeping bags and camping stoves. Let: Event A = owns a tent Event B = owns a sleeping bag Event C = owns a camping stove and let the sample space be the 20 people questioned. a. Find P(A)‚ P(B)‚ P(C)‚ P(A C)‚ P(B C). b

Operating Cost/hour The main assumption to work upon the scenarios is that the numbers generated for the different variables remain the same across the years. Initially‚ a base scenario is built and a profit-and-loss account for a typical year of operation is derived using the most likely values of the different parameters. Upon construction of the base scenario‚ the

quantum dice. According to Benford’s law‚ numbers cumulative biased towards lower digits. This law can be used to identify fraud in dollar amounts. Then‚ the writer introduces two definitions of randomness‚ one is Frequency interpretation: a number is random if comes up in frequency one way or another with expected frequency (judge sample by the way it turned out); another is Subjective interpretation: number coming up can be predicted (judge sample by way it was produced).

probabilities. Probability Distribution may also be: A discrete probability distribution is an arrangement of the probabilities associated with the values of a variable that can assume a limited or finite number of values (outcomes) while a continuous probability distribution is an arrangement of probabilities associated with the values of a variable that can assume an infinite number of possible values (outcomes).

In a poll‚ respondents were asked if they have traveled to Europe. 68 respondents indicated that they have traveled to Europe and 124 respondents said that they have not traveled to Europe. If one of these respondents is randomly selected‚ what is the probability of getting someone who has traveled to Europe? Outcome: selecting someone who has been

repairs is x = 6*square root (sqrt) of r‚ where r is the generated random number. First‚ a random number was generated. The next step to determine the time between repairs was to use the probability function of x=6*sqrt of r. The results of this calculation were placed in the second column of the excel worksheet. A third column was created to determine the cumulative time between the breakdowns. The same process continued: finding a random number‚ using excel function RAND()‚ using the formula‚ x=6*sqrt
