TOPIC:Classical definition of probability.

An automobile manufacturing plant produced
38
vehicles today:
15
were trucks,
10
were vans, and
13
were sedans. Plant managers are going to select two of these
vehicles for a thorough inspection. The first vehicle will be
selected at random, and then the second vehicle will be selected at
random from the remaining vehicles. What is the probability that
the first vehicle selected is a truck and the second vehicle is a
sedan?

Last week, 108 cars received parking violations in the green
parking lot. Of these, 27 had unpaid parking tickets from a
previous violation. Assuming that last week was a random sample of
all parking violators, find the width of the 90 percent confidence
interval for the percentage (correct to four decimal places) of
parking violators that have prior unpaid parking tickets. Note:

A small parking lot has 3 spaces (bays). Vehicles arrive
randomly (according to a Poisson process) at an average rate of 6
vehicles per hour. The parking time has an exponential distribution
with a mean of 30 minutes. If a vehicle arrives when the three
parking spaces are occupied, it leaves immediately without waiting
or returning.
Find the percentage of lost customers, i.e., vehicles that
arrive but cannot park due to full occupancy.
Find the average number of vehicles in...

σ=63.6. A random sample of size n=24 is drawn.
Find the probability that a single randomly selected value is
between 25.1 and 57.5. Round your answer to four
decimal places. to find answer
P(25.1<X<57.5)=

find a parking spot in the Costco parking lot follows a normal
distribution with a mean of 4.5 minutes and a standard deviation of
1.2 minutes.

Part 1: The length of time it takes to find a parking space at 9
A.M. follows a normal distribution with a mean of 6 minutes and a
standard deviation of 3 minutes.
Find the probability that it takes at least 9 minutes to find a
parking space. (Round your answer to four decimal
places.)
