A set is a well-defined collection of objects denoted by capital letters. Elements are denoted by lowercase letters and membership denoted by ∈. Universal set U is assumed to be the foundation for all sets. Empty set ∅ is the only one and a subset of all other sets
A set is a collection of distinct, well-defined objects forming a group. Elements are enclosed in curly brackets and separated by commas. The number of elements in a set is denoted by n(A)
Mutually exclusive events cannot occur simultaneously. The probability of two events occurring together is zero. The sum of probabilities of mutually exclusive events is always less than 1
Sets represent finite collections of objects, with elements being the objects within a set. Sets can be represented in statement, roster, or set builder notation. Venn diagrams visually illustrate relationships between different sets
A set is a collection of well-defined objects sharing a common property. Sets are named and represented in capital letters. Elements are represented by lowercase letters. Sets are enclosed in curly brackets with commas
