That 2/3 (two out of three) chance comes from the fact in the initial door choice, the player has a 1/3 (one out of three) chance of picking the door with the car. There is a 2/3 (two out of three) chance if the car is behind one of the other two doors. If the player could switch from their one" door to the other two doors this would improve their chances. The fact that the host reveals that one of the other doors contains a goat does not change this probability. The player is still effectively swapping their one" door for the other two (even though one of them has been opened).
These are the options:
1. (Lose): If the player picks the car, then the host will show a goat. Then if the player changes their choice, they will get a goat .
2. (Win) : If the player picks a goat, then the host will show the other goat. Then if the player changes their choice, they will get a car.
3. (Win) : If the player picks the other goat, then the host will show the first goat. Then if the player changes their choice, they will get a car.
So, it is true that if the player changes (switches) then the player will win a car two times out of three.
Emergency telephone number
An emergency telephone number is a telephone number that can be used to quickly contact emergency services for assistance. Emergency services usually include police, medical, or firefighting public services. Many countries' public telephone networks have a single emergency telephone number, sometimes known as the universal emergency telephone number or the emergency services number. Most emergency service numbers are 3 digits long so that they can be dialed quickly and remembered easily. Some countries have a different emergency number for each of the different emergency services and are different only by the last digit.
In Europe, the telephone number for emergency services is 1-1-2. In North America, the number for emergency services is 9-1-1. It can be dialed from any phone connected to a network, as a cellular service plan isn't required or charged for emergency calls. Some countries, such as Israel, maintains separate but consecutive numbers for police, fire, and medical services. When the number is dialed on the phone keypad, the call is routed to the nearest emergency telephone operating center. This center is oftentimes found within the same city or town that the call is made from. This provides a strong connection and allows emergency services to get to the location better. In some areas, calls are able to be traced on a map with GPS from cell towers. This can be helpful if a person calls but is unable to speak or if the telephone connection line disconnected before the call was ended intentionally.
The ability to contact emergency services has changed in recent years as technology has advanced. Some mobile devices like the Apple iPhone and Apple Watch and mobile applications such as Noonlight offer capabilities to contact emergency services without having to call or speak to an emergency phone operator. These features are still being tested and developed by using a smart phone's ability to maintain a very accurate GPS location.

Satellite city
Satellite cities are smaller cities that are near to a large city that is the center of a metropolitan area. They are different from suburbs, subdivisions and bedroom communities because they have their own centre. Satellite cities could be separate cities outside of the larger metropolitan areas. However, working as part of a metropolis, a satellite city gets "cross-commuting" (people living in the city working outside of the city and people from other places working in the city). For example, London has several satellite cities, like Brentwood, Crawley and Chelmsford. New Haven and Bridgeport are among the satellites of New York City. Ipswich, Queensland, is a satellite to Brisbane (Australia) and Kitchener and Guelph, to Toronto (Canada).
Satellite cities are almost self sufficient in terms of amenities and facilities. They usually have all of the things to term them as a separate city but they rely on the parent city or the nearby larger metropolitan area for some of their needs like education or employment.Shanty town
Shanty towns are slums on the outskirts of many cities – especially in third world countries. Normally there are not many shanty towns in more economically developed countries. Often of low cost, with houses badly built with plywood, corrugated metal, sheets of plastic, cardboard or any available material. Often irregular structures good enough to keep the rain away or to protect from the summer sun. Pets and animals are often left to roam for food and water.
Lack of clean water, sanitation and toilets often make people, especially children, more exposed to illnesses such as hepatitis and cholera.
Many are built on land without a permit and often have no roads, numbered street, electricity or telephone lines. Some homes in shanty towns have some services but they are unkept and pose health and fire hazards. Sometimes shanty towns can take up whole parts of a city and may include millions of dwellers – such as in the cities of Brazil- see Favelas.
Many shanty town settlements are built on the banks of rivers and as a result the residents suffer the effect of floods or from industrial toxins in the water. Some are built close to rubbish dumps.
Residents of shanty towns often have poor health, lack education, suffer from high levels of crime and suicide, and have a shorter life expectancy.
Pterodactyloidea
Pterodactyloidea is the suborder of short-tailed pterosaurs. Their fossil record starts in the middle Jurassic. They became extinct in the K/T extinction event at the end of the Cretaceous period. "Pterodactylus", "Pteranodon" and "Quetzalcoatlus" are in this suborder.
In 2014 remains of the earliest pterodactyloid was found in China. It is called "Kryptodrakon". Its minimum age was 162.7 million years ago (mya). This is about five million years older than any previously known confirmed specimens.
Recent work shows that the group had more variety at the end of the Cretaceous than was thought earlier. In the early 2010s, several new pterosaur taxa were discovered dating to the late Cretaceous. These finds include some small sized pterosaur species.
At the end of the Cretaceous period, the Cretaceous–Paleogene extinction event, which made all non-avian and most avian dinosaurs, as well as many other animals, extinct. The pterosaurs seem to have gone extinct in this event.
This is the classification of the different divisions of pterodactyloidea:
Michael Praetorius
Michael Praetorius (born Creuzburg an der Werra, near Eisenach 15 February 1571? ; died Wolfenbüttel, 15 February 1621) was a German composer, organist and music theorist. He was one of the most important composers of his day and he wrote lots of different kinds of music. A lot of his music is based on hymns of the Protestant church.
We are not quite certain about the date of his birth. He was born at a time when there was a lot of argument about religion in Germany. His father was a strict Lutheran and lost his job more than once because of his beliefs. We know very little about the life of Praetorius. He seems to have gone to the Lateinschule (“Latin School”) in Torgau where he had music lessons from Michael Voigt. He probably never had music lessons after he left school. Then he went to the University of Frankfurt an der Oder. There Praetorius graduated in divinity. Afterwards he found a job as organist to the Duke of Brunswick-Wolfenbüttel. He soon earned a good salary. He married in 1603 and had two sons.
Although he had his job in Wolfenbüttel for many years he also worked a lot in Dresden where he met Heinrich Schütz and in Magdeburg where he met Samuel Scheidt. His health was not good, possibly because he worked so hard. When he died he left a lot of money to the poor.
