A constructor has two subcontractors for his excavation work. Experience shows that in 60% of ne time, subcontractor A was available to do a job, whereas subcontractor B was available 80% f the time. Also, the contractor is able to get at least one of these two subcontractors 90% of the me. a. What is the probability that both subcontractors will be available to do the next job b. If the contractor learned that subcontractor A is not available for the job, what is the probability that the other subcontractor will be available c. Suppose Ea denotes the event that subcontractor A is available, and Es denotes that subcontractor B is available. i. Are Es and En statistically independent? Explain ii. Are Ea and Es mutually exhaustive? Explain iii. Are Es and Es collectively exhaustive? Explain

3.12 Mark is deciding which route to take to work. His choices are I = the Interstate and F = Fifth Street.• P(I) = 0.44 and P(F) = 0.55• P(I AND F) = 0 because Mark will take only one route to work.What is the probability of P(I OR F)?
To generate leads for new business, Gustin Investment Services offers free financial planning seminars at major hotels in Southwest Florida. Gustin conducts seminars for groups of 25 individuals. Each seminar costs Gustin $3,400, and the commission for each new account opened is $4,900. Gustin estimates that for each individual attending the seminar, there is a 0.01 probability that he/she will open a new account. Determine the equation for computing Gustin's profit per seminar, given static values of the relevant parameters. Profit =(New accounts opened x _______)-_________ Construct a simulation model to analyze the profitability of Gustin's seminars. Would you recommend that Gustin continue running the seminars? (Use at least 1,000 trials. Round your answer to two decimal places.) What is the minimum number of attendees (in a multiple of five, i.e., 25, 30, 35, …) that Gustin needs before a seminar's average profit is greater than zero? =______ attendees

For the project above, suppose our rework loop was “longer.” That is, in the earlier question, we assumed that, after finishing A4 we have a 20% probability of going back to A3. Instead, assume that after completing A4, there is a 5% chance of having to redo A2 (and hence A3 and then A4), there is a 15% chance of having to redo A3 (and hence A4 as well). b) What is the probability of completing the project in 14 or fewer days? (Please enter the percentage of probability without the percentage sign)
A student will take two trainee selection exams for companies A and B, respectively. He estimates the probability that he will pass the exam.Company A's selection rate is 2/3. In company B, the probability of approval is 3/4. Finally, the probability of being approved in both processes simultaneously is of 50%. Under these conditions, what is the probability of passing only one of the companies?

A store specializing in mountain bikes is to open in one of two malls. If the first mall is selected, the store anticipates a yearly profit of $1,425,000 if successful and a yearly loss of $475,000 otherwise. The probability of success is 1. If the second mall is selected, it is estimated that the yearly profit will be $950,000 if successful; 3 otherwise, the annual loss will be $285,000. The probability of success at the second mall is Complete parts (a) through (c) below 4 - a. What is the expected profit for the first mall?
You are a doctor ,a and on average you meet with 30 patients per day. Assuming the NHANES dataset is representative of your patient population, calculate the following. 1. The probability of a single individual having health insurance. = 0.8807812125569134 2. The probability that 3 people in a row will not have health insurance. 3. The probability that 1/3 of your 30 patients for the day do not have health insurance
Dace is a political analyst for a presidential candidate (Aspirant A) with two strong competitors (Aspirants B and C). She analyzed that B and C have exactly the same chance of winning a seat while A has twice the chance of either B and C. With the given information, what is the chance of A in winning.
Please provide steps for how you got the solution to the problem provided below. A machine is used to produce one of each of two types of product (A and B) on alternating days, i.e., if A is produced today then B will be produced tomorrow and vice versa. Each day, there is a probability that the machine malfunctions. Malfunction probability after a day of operation is 0.03 when producing A and 0.07 when producing B. Once the machine malfunctions, it is no longer operable and will not be replaced until sometime in the future (beyond modeling horizon). Model the system as a Markov chain (give transition matrix on your paper). Suppose that on Monday product A was produced. Find the probability that the machine is still operable by the morning of Thursday. Your model should have a state ”malfunction”, which cannot transition to any other state other than itself.
From observations of the weather, it is known that on October 20 the probability of rain is 0.85. A certain forecast method for October 20 is correct 0.9 times if rain is predicted and 0.75 times if no rain is predicted. How much information does a real weather forecast provide 20 th of October? n.b the picture is example of solution
