Plzzz solve and choose correct option.
A poker player has either good luck or bad luck each time she plays poker. She notices that if she has good luck one time, then she has good luck the next time with probability 0.2 and if she has bad luck one time, then she has good luck the next time with probability 0.4. What fraction of the time in the long run does the poker player have good luck?
A certain tennis player makes a successful first serve 78% of the time. Assume that each serve is independent of the others. If she serves 9times, what's the probability she gets: Part 1 a) The probability that she gets all 9 serves in is _______________ (Round to three decimal places as needed.). Part 2 b) The probability she gets exactly 4 serves in is _______________ (Round to three decimal places as needed.) Part 3 c) The probability she gets at least 7 serves in is ______________________ (Round to three decimal places as needed.) Part 4 d) The probability that there are no more than 6 serves in is __________ (Round to three decimal places as needed.)
Please provide steps for how you got the solution to the problem provided below. A freelance worker spends her days doing one of two things: working on a project or looking for a new project. Whenever she has a project to work on, she dedicates her full attention to it. On a particular month, she will complete the current project with probability 0.3. After completing project she takes the rest of the month off, and then at the beginning of the next month starts looking for work. On a given month, she will successfully find a new project with probability 0.85. After identifying a new project, she will start working on it at the beginning of the next month. i. Model the status of the worker (looking for a project of busy working a project) as a Markov chain. Give transition matrix. ii. Suppose that on March 1st she started looking for a new project. Find the probability that she will be working on a project during the month of May.
please solve fast in text format...should be in well formatted with use of maths editor tools ...handwritten solution not allowed ...dont use chat gpt
Suppose a weather report indicates that the probability of rain this week is 0.20. This week Next week According to the report, if it rains this week, then the probability of rain next Rain week is 0.33. If it does not rain this week, then the probability of rain next week is 0.17. The tree diagram models this weather report. 0.33 Rain 0.20 Determine the probability that it will not rain for the next two weeks. Express 0.67 No rain your answer as a decimal precise to two decimal places. Rain 0.17 probability = 0.80 No rain 0.83 No rain

Suppose that you repeatedly roll a pair of fair dice and keep track of the sum. What is the probability that you see a sum of 7 before you see an even sum 3 times? (In particular, you keep track of how many evens you roll, and you want the probability that you roll a 7 before you get to 3 evens.
The probability that an applicant will be approved for a mortgage is 0.15. Each applicant has the same probability of being approved and the event that they are approved are independent. What is the probability that out of three applicants, exactly two of them get approved? Enter your answer as a decimal, with three decimal places. For example, if the probability is 15.37%, enter 0.154
SOLVE STEP BY STEP IN DIGITAL FORMAT Urn A contains 2 white and 4 red marbles. Urn B contains 1 white and 1 red marble. A marble is randomly drawn from urn A and placed in urn B. Then a marble is drawn at random from urn B. Find the probability that the marble selected from urn B is red.
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.
Solve Part B only for question 14 and show work for each step of the problem. Please and thank you.
