Have to show work for every problem 4. A company uses three plants to produce a new computer chip. Plant A produces 30% of the chips. Plant B produces 45% of the chips. The rest of the chips are produced by plant C. Each plant has its own defectiv rate. These are: plant A produces 3% defective chips, plant B produces 1% defective chips, plant C produces 5% defective chips. Hint: draw a tree diagram. (a) Construct a tree diagram...
Ex. 10Annie and Alvie have agreed to meet between 5:00 P.M. and 6:00 P.M. for dinner at a local health-food restaurant. Let X = Annie's arrival time and Y= Alvie's arrival time. Suppose X and Yare independent with each uniformly distributed on the interval [5, 6].a. What is the joint pdf of X and Y?b. What is the probability that they both arrive between 5:15 and 5:45?c. If the first one to arrive will wait only 10 min before leaving...
Annie and Alvie have agreed to meet between 5:00 P.M. and 6:00 P.M. for dinner at a local health-food restaurant. Let X = Annie's arrival time and Y = Alvie's arrival time. Suppose X and Y are independent with each uniformly distributed on the interval [5, 6]. Given: f(x)={1 for (5 <= x <= 6) , (5 <= y <= 6) 0 anywhere else (c) If the first one to arrive will wait only 20 min before leaving to eat...
Annie and Alvie have agreed to meet between 5:00 P.M. and 6:00 P.M. for dinner at a local health-food restaurant. Let X- Annie's arrival time and Y-Alvie's arrival time. Suppose X and Y are independent with each uniformly distributed on the interval [5, 6] (a) what is the joint pdf of X and Y? f(x,y) 0 otherwise (x,0 otherwise (a, y) otherwise (r.y)0 otherwise (b) What is the probability that they both arrive between 5:21 and 5:48? (Give answer accurate...
MATH REASON OF PROBABILITY Sonia and Natasha are supposed to meet at a certain location around 5:30 pm. Sonia arrives at some time uniformly distributed between 5:00 pm and 6:00 pm, while Natasha arrives at some time uniformly distributed between 5:15 pm and 6:00 pm. Given that Natasha arrives first, what is the probability that she will not have to wait for more than 10 minutes for Sonia? Hint. Let X be the arrival time (in minutes since 5 pm)...
a) Say you wait for the bus on two independent days. What is the probability that you wait more than 20 minutes on both days? What about the probability of waiting more than 20 minutes on just one of the days? 3. You are to wait for a bus to arrive. The bus arrives every 30 minutes, but you dont know the exact time it will arrive. Thus, you can wait any time between 0 and 30 minutes, and you...

The time between arrivals of taxis is exponentially distributed with a mean of 10 minutes. a) You are fourth in line looking for a taxi. What is the probability that exactly 3 taxis arrive within one hour? b) Suppose the other three parties just decided to take the subway and you are now the first in line for the next taxi. Determine the time t such that the probability you wait less than t minutes from now until the next...
Andrew and Bill are scheduled to meet at Starbucks at a set time, but they are often late for appointments. Each will arrive at Starbucks with a delay between 0 and 1 hour, with all pairs of delays being equally likely. Moreover, both Andrew and Bill shun the conveniences of the modern world, and thus they do not have cell phones to contact each other. The first person to arrive will wait for 20 minutes (1/3 of an hour) but...
Jim, Sergio, Eduardo, and Simone have all been invited to a dinner party. They arrive randomly and each person arrives at a different time. a. In how many ways can they arrive? b. In how many ways can Jim arrive first and Simone last? c. Find the probability that Jim will arrive first and Simone last. (Type an integer.) An apartment complex offers apartments with four different options, designated by A through D. There are an equal number of apartments...
