A finite set, possibly.
If the set has n elements, the number of subsets (the power set) has 2n members.
No set number.
The mean is the average; the total of the members of the set divided by the number of members n the set.
It is a one-to-one correspondence and it is defined as situation which occurs when the members of one set can be evenly matched with the members of a second set.
That's the average value of all the members of the set.
That's the average value of all the members of the set.
The objects within a number set can be caled as "Elements" or "members".
A set with 27 members has 2^27 = 134217728 subsets - including itself and the null set.
The members of a given set are called "elements" or "members" of that set. For example, if you have a set of numbers, each individual number is considered an element of that set. In mathematical terms, the notation often used is to denote a set with curly brackets, with its elements listed inside.
If it weren't considered a set, lots of rules would need exceptions for the case there are no members in a set.
This is the Arithmetic Mean (also known as the average).
No, a finite set can be a set of anything - as long as it has a finite number of members.Some examples of finite sets are:the set of black chess pieces in a chess set (16 members)the set of all red 2010 cars made by Ford (unknown but finite number of members)the set of planets orbiting our sun (8 members)the set of numbers between 14 and 23 that are integer multiples of pi (3 members) {5*pi, 6*pi, 7*pi} The elements of this set are all irrational numbersthe set of marbles inside a pint jar (unknown but finite number of members)the set of bowling balls in a 2 liter soda bottle (0 members as a bowling ball is too big to fit in a 2 liter soda bottle)etc.
