Could you please help me with this example >>>with the explanation (why)?

(See attached file for full problem description)

A group of tourists is traveling in outback Australia. They are planning to travel from Looloo to Pearl Rock via the towns of Mt Tedious, Nimboi Creek, and Ommata. The distances involved are Looloo to Mt Tedious is 71km, Mt Tedious to Nimboi Creek is 10km, Nimboi Creek to Ommata is 50km, and Ommata to Pearl Rock is 73km. The tourists' car has a fuel tank that will allow it to drive 100km before refueling. However, there is a fuel strike on and so there is a possibility that each of the towns might not have fuel. If the tourists start at Looloo with a full tank of fuel and intend to refuel every chance they get, which of the following fault trees (1-8) most accurately describes the probability that they will get to Pearl Rock without being delayed by having to wait in one of the intermediate towns for the fuel strike to finish? (In the following diagram M means there is fuel at Mt Tedious, N means there is fuel at Nimboi Creek, and O means there is fuel at Ommata)...

The distances involved are Looloo to Mt Tedious is 71km, Mt Tedious to Nimboi Creek is 10km, Nimboi Creek to Ommata is 50km, and Ommata to Pearl Rock is 73km.
The total distance =71+10+50+73 =204 Km
The tank capacity is 100 Km.
Let us see what the alternatives available to the tourists. ...

Solution Summary

This solution determines and explains the correct fault tree to most accurate describe the probability that the ship will get to Pearl Rock without being delayed by having to wait in one of the intermediate towns for the fuel strike to finish

A fuel gauge uses a capacitor to determine the height of the fuel in a tank. The effective dielectric constant K_eff changes from a value of 1 when the tank is empty to a value of K, the dielectric constant of the fuel, when the tank is full. The appropriate electronic circuitry can determine the effective dielectric constant of

If we use octane (C8 H18 ) as the representative of what is contained in gasoline, and compare it to ethanol (C2H5OH), currently a promising substitute for gasoline, what will be the energy difference on a per gram basis for the two? For the reaction of octane with oxygen to produce carbon dioxide and gaseous water, 48.1 kJ of h

Filling a tank. A water tank has an inlet pipe and a drain pipe. A full tank can be emptied in 30 minutes if the drain is opened and an empty tank can be filled in 45 minutes with the inlet pipe opened. If both pipes are accidentally opened when the tank is full, then how long will it take to empty the tank?

Suppose that the weight (in pounds) of an airplane is a linear function of the total amount of fuel (in gallons) in its tank. When graphed, the function gives a line with a slope of 6.4.
With 55 gallons of fuel in its tank, the airplane has a weight of 2252 pounds. What is the weight of the plane with 22 gallons of fuel in i

Water fills a tank at a rate of 150 litres during the first hour, 350 litres during the second hour, 550 litres during the third hour and so on. Find the number of hours necessary to fill a rectangular tank 16m x 9m x 9m.

A full tank can be emptied in 30 minutes if the drain is opened and an empty tank can be filled in 45 minutes with the inlet pipe opened. If both pipes are accidentally opened when the tank is full, then how long will it take to empty the tank?

I need solutions to the question a) only, please.
For the system shown below where each labeled box indicates a valve that is normally open:
(a) Draw a faulttree for the top event "no flow out of the system."
(b) Find the minimal cutsets
(c) Find the exact top event probability using the basic event probabilities given

An aquarium tank can hold 7700 liters of water. There are two pipes that can be used to fill the tank. The first pipe alone can fill the tank in 77 minutes. The second pipe can fill the tank in 44 minutes by itself. When both pipes are working together, how long does it take them to fill the tank?

A rigid tank contains 5 kg of an ideal gas at atm and 40° C. Now valve is open, and half of mass of the gas is allowed to escape. If the final pressure in the tank is 1.5 atm, what is the final temperature in the tank?
