(14 pts) Clearly state which distribution you are using to arrive at your solution, for all parts of this question. Suppose that on average 4 tornados occur in 8 years in a county in Oklahoma. If the occurrence of tornados follows a Poisson process: (a) What is the probability that less than 6 years pass before 2 tornados occur? (b) What is the probability that there will be at least one tornado next year? (c) What is the probability that...
The probability that a certain state will be hit by a major tornado (category F4 or F5) in any single year is Complete parts (a) through (d) below a. What is the probability that the state will be hit by a major tornado two years in a row? (Simplify your answer. Round to five decimal places as needed.) b. What is the probability that the state will be hit by a major tornado in three consecutive yours? (Simplify your answer Round to...
There are five Oklahoma State Officials: Governor (G), Lieutenant Governer (L), Secretary of State (S), Attorney General (A), and Treasurer (T). Take all possible samples without replacement of size 3 that can be obtained from the population of five officials. (Note: There are 10 possible samples! Make sure to list out the sample space.) (a) What is the probability that the governor is included in the sample? (b) What is the probability that the governor, attorney general and the treasurer...
a) If the process begins in state 1, what is the probability that absorption will occur after exactly five steps (i.e., the absorbing step will be reached on the fifth step)? b) If the process begins in state 2, what is the probability that absorption will occur in six steps or fewer? You are given the following transition probability graph:
Earthquakes occur in the United States according to a Poisson process having a rate of 0.25 per day. Suppose we begin counting earthquakes at some point in time. a. What is the probability that 6 earthquakes occur in July 2050? b. On average, when will the 50th earthquake occur? 25 Example 4.5 What is the probability that 2 or more earthquakes occur over a 50-day period? c. d. What is the probability that it takes more than 10 days until...
Even in Tornado Alley, the chances of a tornado striking any particular location are pretty small. To illustrate this point, let’s estimate the risk in the state of Kansas which averages 80 tornadoes per year. Explain why we chose Kansas for this problem instead of Texas, given that Texas averages more tornadoes (140) per year. To frame your answer, note that the area of Kansas is approximately 211,800 mi2while the area of Texas is about 676,600 mi2. You should include...
The probability of an event that must occur is 2. State whether the statement is true or false Every probability is a number between 0 and 1 inclusive 3.The result of an experiment is called an 4. In a sample of 50,000 first-born babies, 5 were found to have Prader-Willi syndrome. Find the probability that a family's first child will be born with this syndrome. The probability of an event that cannot occur is QUESTION 6 The sum of...
The number of complaints per day, X, received by a cable TV distributor has the probability distribution 2. 0 .4 .2 a) Find the expected number of complaints per day 0C6. 4)I(o.3)2 (0.1) 3( 0,2) b) Find the standard deviation of the number of complaints What is the approximate probability that the distributor receives a total of more than 100 complaints in 90 days? c)
C1: Snow Manufacturing Co. has 6 machines that perform a particular task. Breakdowns occur frequently for this machine. Past records indicate that the number of breakdowns that occur each day is described by the following probability distribution: SK2: 5 marks Number of Probability Breakdowns 0.2 0.3 0.4 More than 3 0.0 Required: 1. What is the expected number of breakdowns in any given day? (2 marks) 2. What is the variance for this distribution? (1 mark) 3. What is the...
Problem 1 While performing scheduling work on a project you have determined that one activity has a great deal of variability. A sample of times (30) the task has been completed is provided the table below. Assume that the task is considered to be "late" if the task duration is two days greater than the mean value (rounded to the nearest whole day), and "early" if the task duration is two days less than the mean value (rounded to the...
