Discrete math unions and intersections
How do you find the intersection of A and B?
Set operations Definition: Let A and B be sets. The intersection of A and B, denoted by A B, is the set that contains those elements that are in both A and B. Alternate: A B = { x | x A x B }.
What is discrete math?
Discrete math = study of the discrete structures used to represent discrete objects Many discrete structures are built using sets Sets = collection of objects
How do you find the Union of A and B?
Definition: Let A and B be sets. The union of A and B, denoted by A B, is the set that contains those elements that are either in or in B, or in both. Alternate: A B = { x | x A x B }.
What is a B in discrete mathematics for CS?
A B CS 441 Discrete mathematics for CS M. Hauskrecht Set operations Definition: Let A and B be sets. The intersection of A and B, denoted by A B, is the set that contains those elements that are in both A and B. • Alternate: A B = { x | x A x B }. Example: • A = {1,2,3,6} B = { 2, 4, 6, 9} • A B = { 2, 6 } U A B

When is it appropriate to use unions, intersections, or complements in determining probability? Why is the addition rule related to unions, intersections and complements? Mathematicians determine the independence of events A and B by examining if the product of the probabilities of A and B equals the probability of A and B occurring together.

Random variables can be either discrete or continuous. Discrete variables and their distributions are explained and students explore probability distributions in general and a specific, often used distribution called the binomial distribution. Students also begin to discuss and explore the properties of a normal distribution and its applications.
