- Find the probabilities using either geometric distribution, the Poisson distribution or the binomial distribution. A football player completes a pass 65.3% of the time. Find the probability that (a) the first pass he completes is the second pass, (b) the first pass he completes is the first or second pass, and (c) he does not complete his first two passesCondom Failure Rate: According to the Department of Health and Human Services, the failure rate for male condoms is 18%. The accompanying table is based on the failure rate of 18%, where x represents the number of condoms that fail when six are tested. x P(x) 0 0.304 1 0.400 2 0.220 3 0.064 4 0.011 5 0.001 6 0+ Does the table describe a probability distribution? Why or Why not? Assuming that the table does describe a probability distribution, find its mean? Assuming that the table does describe a probability distribution, find its standard deviation? If 6 condoms are tested and 5 of them fail, is 5 a significantly high number of failures? Why or Why not? What does the symbol 0+ represent?[Queuing Theory - Operation research] The take-out counter at an ice-cream parlor is serviced by one attendant. Customers arrive according to a Poisson process, at a mean arrival rate of 30 per hour. They are serviced on a FCFS basis, and because of the quality of the ice cream, they are willing to wait if necessary. The service time per customer appears to be exponentially distributed, with a mean of 1.5 minutes. Determine the probability that a customer will have to spend more than 15 minutes in the queue
- Find the expected value for the random variable whose probability function graph is displayed here. What is the expected value of the random variable? (Type an integer or a decimal.) 0.5- 0.4- 0.3- 0.2- 0.1- 0- 0 ♫ 2 3 4 5 1 1Probabilities: Sampling Means ing: Now that we know when we can use the normal distribution, we can use the Empirical Rule and the Normal Table (opens in new window) to find the probabilities. Example 1 Recall our earlier scenario: The Federal Pell Grant Program provides need-based grants to low-income undergraduate and certain post-baccalaureate students to promote access to post-secondary education. According to the National Post-secondary Student Aid Study conducted by the U. S. Department of Education in 2008, the average Pell grant award for 2007-2008 was $2, 600. Assume that the standard deviation in Pell grants awards was $500. If we randomly sample 36 Pell grant recipients, would you be surprised if the mean grant amount for the sample was $2, 940? 1. Can we use use the normal approximation? + (Click to view hint) 2. What theorem states that we can use the normal approximation? The Limit Theorem 3. If the population mean is 2600, how can we determine if 2940 is unusual? a. If…(a)Consider the probability distributions you have studied so far.

- BINOMIAL DISTRIBUTION 35% are successes. In a sample of 6 trials, what is the probability that 3 will be successes?Poisson Distribution: (Please answer as soon as possible) A new automated production process averages 3.3 breakdowns per day. Because of the cost associated with a breakdown, management is concerned about the possibility of having 4 or more breakdowns during a day. Assume that breakdowns occur randomly, that the probability of a breakdown is the same for any two time intervals of equal length, and that breakdowns in one period are independent of breakdowns in other periods. What is the probability of having 4 or more breakdowns during a day? (to 4 decimals)In a national survey college students were asked, "How often do you wear a seat belt when riding in a car driven by someone else?" The response frequencies appear in the table to the right. Response FrequencyFrequency Never 124 Rarely 305 Sometimes 544 Most of the time 1217 Always 2641 Construct a probability model for seat-belt use by a passenger
