Conditional Probability to Determine Independence

By Paris

  • There is a 14% chance of feeling "strange" (ringing in ears, fuzzy head, etc.) prior to a migraine. This indication that a person is about to have a migraine is known as "aura" (denote this event by A)

  • There is a 26% chance of simply experiencing a headache (denote this event by H)

  • There is a 5% chance of experiencing both side effects (A and H).

Are the two side effects independent of each other?
