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 :)(adsbygoogle = window.adsbygoogle || []).push({});

[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]
