Drift is caused by random sampling error or other chance events. what is another name for this phenomenon?

I believe the answer is: Luck

For example, let's say that for 99.99% of the time, people who fall down from 20th floor of a building would be resulted in death. But, due to a certain sampling error or chance of events, there is two men just passing by bringing a spring bed order as person A fall from the 20th floor, which saved his life. In this case, that person A is experiencing luck.

saving account is right

panem is a communist totalitarian dictatorship where all the resources and how they are allocated belongs to the capitol. the districts exist only to provide goods and services for the capital and most of the citizens live in poverty. it is a police state where the "peacekeepers" use force and threats to keep the people under control. dissent is outlawed and those who disobey the law are executed, flogged, or turned into avoxes. the games are another means in which the ruling elite in the capitol exert their power over the districts. when reading the books i drew parallels between panem and the soviet union and north korea. in no way is panem capitalist. the people in the capitol are wealthy but the majority of them are involved in the government somehow. it was the same way in the former soviet union where bigwigs in the communist party and high ranking government officials were given access to goods, services, medical treatments not available to the general public. if you think panem has a capitalist economy you need to brush up on your economics.
