For example, the empty set and the set of letters of English alphabet are finite sets, whereas the set of even positive integers, {2,4,6,…..}, is infinite. If a set A is finite, we let n(A) or #(A) denote the number of elements of ...

This logical connective is ambiguous in everyday language, sometimes being used in the inclusive sense (in which "p or q" is taken to mean "v or q, or both p and q") and other times being used in the exclusive sense (in which "» or q" means "p or q, but not both"). As we have explicit ...

... Example: S = {1, 2, 3} = {1, 3, 2} = {2,1,3} etc. If a set contains too many elements to be listed, then we use the ellipsis or “three dot notation”. Example: The set of all positive even integers less than 41 can be described by X={2, 4, …, 40} The set of all positive odd integers can be described ...
