Basics Definition From Set Theory

Here are some common definitions found in Set Operations:

• Complement: Is the set that contains all the elements that don't belong to an example set S. This can be mathematically written as S^c = U \ A
• Union: Is the combination of two sets such that all elements that belong to given sets A or B(or both sets) are contained in the new set A ∪ B
• Intersection: Is the combination of two sets such that only elements that belong to given sets A and B are contained in the new set A ∩ B
• Disjoint: Is when two given sets do not have any elements in common. Therefore, their intersection would be empty
• Partition: Is when there is a set A and smaller sets within it that are all disjoint sets. In this scenario, the collection of smaller sets within set A can be said to be a partition of set A
• Sample space: Is the set of all possible outcomes of an experiment
• Probability law: Is a law of probability that assigns a nonnegative number, P, to a set A where the P represents our knowledge or belief about the collective probability of the elements of set A.
• Event: Is a subset of the sample space also known as a potential outcome from a set of possible outcomes
• Collectively Exhaustive: Is a probability related concept where at least one of the events in a given sample space must occur(or have a 100% probability)
• Mutually Exclusive: Is a probability related concept where two events cannot occur at the same time or simultaneously. This is also known as disjoint events
