According to the Migraine Research Foundation, nearly 1 in 4 US households includes someone with a migraine. Amazingly, 12% of the populationincluding childrensuffers from migraines. 18% of American women, 6% of men, and 10% of children experience migraines. 35% of the population suffering from migraines finds Sumitriptan effective in treating migraines. 65% of the population treats migraines with over the counter (OTC) medications. 8% of the population chooses to treat migraines with Sumitriptan and OTC medications. Some doctors decided to test a treatment using 100% pure oxygen as a therapeutic measure, which they started administering to migraine patients in the ER (assume those coming to the ER are those who do not use Sumitriptan or OTC). What is the probability that a migraine sufferer uses 100% oxygen as treatment? Is a patient receiving Sumitriptan treatment independent of a patient going to the ER?
