The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. (ii) Suppose that you have already been waiting for one hour for a taxi. What is the probability that one arrives within the next 10 minutes? (iii) Determine x such that the probability that you wait more than x minutes is 0.10. (iv) Determine x such that the probability that you wait less than x minutes is 0.90.
The inter arrival time between bus arrivals is exponentially distributed with an average time of 14minutes. Suppose that you have already been waiting at the bus stop for 3 minutes. Find the probability that the bus will arrive within the next 4minutes.
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...
answer all parts and show your work! thank you The inter-arrival times (in hours) between train arrivals to a station has Exponential distribution with mean of 0.25 hours (a) What is the distribution of S2, the time until arrival of the second train? Find the expected waiting time for the second train to arrive. (b) Let N represent the number of trains that arrive to the station in 1 hours. What is the distribution of N? Find the expected number...
Analysis of arrivals to a single pump gas station has shown that the times between arrivals can be depicted by negative exponential distribution with a mean of 10 minutes. Service times were observed to be distributed negative exponentially, as well, with a mean time of 6 minutes. What is the steady-state mean number of customers at the station and the steady-state mean number that are waiting?
A bus comes by every 14 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 14 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. c. The probability that the person will wait more than 4 minutes is _____ d. Suppose that the person has already been waiting for 0.5 minutes. Find the probability that the...
A bus comes by every 15 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 15 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. a. The mean of this distribution is b. The standard deviation is c. The probability that the person will wait more than 5 minutes is d. Suppose that the person has...
A bus comes by every 13 minutes. The times from when a person arives at the busstop until the bus arrives follows a Uniform distribution from 0 to 13 minutes. A person arrives at the bus stop at a randomly selected time. Round to 4 decimal places where possible. a. The mean of this distribution is b. The standard deviation is ? c. The probability that the person will wait more than 7 minutes is ? d. Suppose that the...
1. Suppose that the time between arrivals of insect pollinators to a flowering plant is exponentially distributed with parameter = 0.3hr • Find the mean and standard deviation of the waiting time between suc- cessive pollinator arrivals . If a pollinator just left the plant, what is the probability that you will have to wait for more than three hours before the next pollinator arrives? 2019:4 Fall, MATH5680:001 Intro to Theory of Probability
Let X = the time between two successive arrivals (in minutes) at a drive thru window. Suppose X is exponentially distributed, and that the average time between successive arrivals at the drive thru window is 1.2 minutes. What is the value of lambda, the parameter of exponential distribution? What is the probability that the next drive thru arrival is between 1 to 4 minutes from now? What is the probability that the next drive thru arrival is greater than 2...
