What does the term "combination" refer to in probability theory?

• The selection of objects where the order is important

• The selection of objects from a group where the order doesn't matter

• The total number of outcomes for a given event

• The outcome of one event affecting another event

What is meant by "complement" in the context of probability?

• The set of outcomes that are in an event

• The set of outcomes that are not in an event

What is the "factorial" of a number in mathematics?

• The sum of all positive integers up to that number

• The division of that number by all positive integers up to it

• The subtraction of all positive integers from that number

What principle is described by the "Fundamental Counting Principle"?

• The probability of an event occurring given another event has occurred

• The total number of outcomes of a sequence of events is the product of the number of outcomes for each event

• The selection of objects from a group without considering order

What does the "Law of Large Numbers" state?

• The product of all positive integers from 1 to a given number

• The selection of objects where the order doesn't matter
