Describe the intersection of events in a sample space. For example: Event A contains soccer players, event B contains football players. Intersection of the sets is players that participate in both soccer and football.

Essential Understandings

Concrete:

  • Given two sets of objects, determine what they have in common.
    For example:(To make it easy, notice that what they have in common is in bold)

    Let A = {1 orange, 1 pineapple, 1 banana, 1 apple} and B = { 1 spoon, 1 orange, 1 knife, 1 fork, 1 apple}
    A∩B = {1 orange, 1 apple}
Representation:
  • Understand that:
    A∩B represents the intersection of sets A and B.
    This is all the items which appear in set A and in set B.

  • Given two sets of objects, determine what they have in common.
    For example:

    Intersection of sets A and B: examples of Set Notation, Venn Diagram and answer based on Venn Diagram.

Date Adopted or Revised: 06/14 Cluster: Understand independence and conditional probability and use them to interpret data. (Algebra 2 - Additional Cluster)

Clusters should not be sorted from Major to Supporting and then taught in that order. To do so would strip the coherence of the mathematical ideas and miss the opportunity to enhance the major work of the grade with the supporting clusters.
