Homework Help: Set Notation:

  1. Feb 2, 2007 #1
    I'm having a little difficulty understaning the notation used in my probability class. Would someone tell me if I'm on the right track with it :)


    [tex] A\cup B [/tex] is the event "either A or B or both." Does this mean that A and B can happen together and that A or B can happen alone?


    [tex] A\cap B is the event "both A and B" Does this mean that both events MUST happen? [/tex]

    Now I'm getting a message that my reply is too short! How long does it have to be?
