The bus to Union Station leaves every 30 minutes and is uniformly distributed. Find the probability that a randomly chosen person arriving at a random time will wait between 10 and 15 minutes? (Round your answer to 3 decimal places) The completion times to run a road race are normally distributed with a mean of 190 minutes and a standard deviation of 21 minutes. a) What is the probability that a randomly selected runner will finish the race in less than 150 minutes? (Round your answer to 4 decimal places)

1. The bus to Union Station leaves every 30 minutes and is uniformly distributed. Find the probability that a randomly chosen person arriving at a randome time will wait between 10 and 15 minutes ? (around your answer to 3 decimal places)

You arrive at a bus stop to wait for a bus that comes by once every 30 minutes. You don't know what time the last bus came by. The time x that you wait before the bus arrives is uniformly distributed on the interval from 0 to 30 minutes. (Round your answers to four decimal places.) (a) What is the probability that you will have to wait longer than 17 minutes? (b) What is the probability that you will have to wait less than 13 minutes? (c) What is the probability that you will wait between 10 and 23 minutes?

A train arrives at a station every 15 minutes. It is assumed that the waiting time for a particular individual is a random variable with a continuous uniform distribution. (a) What is the probability that the individual waits more than 10 minutes? (b) What is the probability that the individual waits between 6 and 12 minutes?
