When did trillion become common in everyday language?

In international trade, commerce and finance, the term has been in use for many years, in financial newspapers and governmental statistics reporting.. If a country's currency exchanged for an American dollar is a large denomination, then millions of Yankee bucks become trillions of local currency. For example, in South Korean currency ( KRW ) very very approximately one thousand Won is equal to one dollar. Thus, if General Motors had purchased a local auto manufacturer for $100 million, the newspapers would report that as being a 100 billion transaction, in local terms. Very soon, the numbers pile up and international trade figures for a month or a year are up in the trillions. I suggest you research the International Monetary Find and World Bank for old data statistics and the "trillion" word first occurrences.

How do you find a reseach study that implemented correational and inferential statistical procedues?

Most likely discipline to use inferential math would be social sciences (they love to infer) I'm not sure if by correational means correlational, but, if it does, social 'scientists' like that a lot, too

How do you compute the Greeks within the Gaussian copula CDO valuation model?

They cannot be coputed directly. It is a static model. You can estimate the Greeks by shifting the market-data inputs, but there are no analytic formulas. Since most firms calculate Greeks by shifting data, regardless of the availability of analytic formulas, this is not a bad possibility. The difficult part is determining which sensitivities you may want to hedge against.

What does perambulating mean?

A perambulator is either

  • a baby transport - a "pram" (which is just a shortening of perambulator). In the USA it is most often called a "stroller".
or
  • a surveyor's wheel - which is used to measure distances. A single wheel is attached to a handle and the device can be pushed or pulled along by a person walking. The circumference of the wheel is known so by tracking the total number of rotations (and fractions of rotation) while dragging or pushing the wheel between any two spots, the distance can be determined.
This fits well with the term Perambulate, which means "walk around". You "walk around" with a baby in a pram. In traditional English law, the term "perambulation" is used specifically to mean "determining the bounds of a legal area by walking around it", meaning physically walking around the region in question - a perambulator (surveyor's wheel) is very useful in that context.

What are the odds of eight matching dice out of ten die in one roll?

The odds of one die being any number is 1 in 1. The odds of any of the next seven dice being the same as the first die is 1 in 6. The odds of the last two being different than the first die is 5 in 6.

The dice are unrelated to each other, and it does not matter in what order they are thrown, so the odds of eight matching dice out of ten dice is (1 in 1)1 (1 in 6)7 (5 in 6)2, or 25 in 10,077,696.
