0.3

Step-by-step explanation:

P (drug/migraine) = P (drug&migraine) / P (migraine)

= (0.1*0.3) / 0.1

= 0.3

Answer:LetAbe the event that the person is taking the drug. We are told thatP (A) = 0.05. LetBbe the event that the person has migraines. We are told thatP (B) = 0.1. Further, we are told thatP (B|A) = 0.3. Using the rules for conditional probability, P (A|B) = P (A∩B) P (B) = P (B|A) P (A) P (B) = 0.3·0.050.1=0.15. The probability that a migraine sufferer takes the drug is 15%.
