What was the real rason the king moved from Paris to Versailles?
Versailles is a small village near Paris in France. It is famous for the enormous castle that Louis XIV (France's greatest King ever, also called the Sun King) had build there (also called Versailles) and made Versailles the capital of France. He wanted a different castle outside Paris (the former Royal residence was in the centre of Paris, the Tuilerie castle). 3 generations of Kings and Queens lived there, until the monarchy got destroyed during the the French revolution and the last King and Queen of France ever, Louis XVI and Marie Antoinette, got killed. Especially Marie Antoinette made significant changes to the Versailles castle. She was the one that introduced bathrooms to the castle, which were highly unusual at that time (she liked to bath every day, when most people only bathed like once a month, tops! It was considered unhealthy to bath). She also decorated a lot of rooms beautifully and chose the furniture. Unfortunately, most of it got destroyed or stolen during the revolution. Today the castle is wonderfully restored and you can visit. It has an amazing historical value.

The ultrasound can determine if they are fraternal or identical. If they are identical then they will share a placenta and they may even share an amniotic sac.

In a multiple choice test what is the probability of getting 7 correct answers?
That's really going to be heavily dependent on whether or not you know something about
the subject material, and also on the total number of questions on the test.
It has even been known to happen from time to time that there are people who will score
100% on one of those, i.e. all correct answers.
Since that happens at a rate that far exceeds random probability, many educators and
administrators have begun to suspect that some of these test-takers may actually be
going so far as to study the material in advance! But the allegation hasn't been proven.
How do you express the probability event?
