- The three-year recidivism rate of parolees in a certain state is about 20%; that is, 20% of parolees end up back in prison within three years. Assume that whether one parolee returns to prison is independent of whether any of the others return. Complete parts a and b below. Find the probability that exactly 6 out of 20 parolees will end up back in prison within three years. The probability that exactly 6 out of 20 parolees will end up back in prison is nothing.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.)A local company has two identical lathe machines which are operated independently.

- 1) A manufacturer will purchase a battery from one of two suppliers. This manufacturer will get the battery from supplier 1 with probability 0.6 and from supplier 2 with probability 0.4. A battery obtained from supplier 1 has a lifetime, which is exponentially distributed with a mean of 6 months. On the other hand, the lifetime of a battery from supplier 2 is again exponentially distributed with a mean of 5 months. What is the probability that the purchased battery (from supplier 1 or 2 with aforementioned probabilities) will last more than 5 months?Given P(A) = 0.10, P(B) = 0.63, P(C) = 0.53 and that events A, B, and C are independent, what is P(A, B, and C). Answer in decimal form. Round to 3 decimal places as needed.Suppose that we perform an experiment where we classify the outcome as either a success or a failure. Let the probability of a success be 0.90.9 . Now we want to repeat this experiment n = 44 times and let the random variable X count the number of successes. Visualize a probability tree for this situation (without actually drawing it out). Round to four decimal places as needed. From each vertex there will be 22 edges going to a success S and a failure F. Since each stage is independent all the edges going to an S will have probability p = . 9.9 and all the edges going to an F will have probability q = . 10.10. If a single path has 2 success and the rest failures (in any order) then the probability of that single path is nothing. Note that these 2 successes may be in any of the 44 stages so there are nothingof these paths which have 2 successes. Therefore, P(X = 2) = nothing.
- Suppose the weather moves between three states 1,2,3. It stays in state 1 for an exponentially distributed number of days with mean 3, then goes to state 2. It stays in state 2 for an exponentially distributed number of days with mean 4, then goes to state 3. It stays in state 3 for an exponentially distributed number of days with mean 1, then goes to state 1. Compute the long-term probability that the weather is in state 1. Write your answer as a decimal.zample 3: Alexis is selling girl scout cookies. She has kept track of the number of boxes of cookies at her customers have purchased over the last 2 years.
