**Migraine and Acupuncture:** Researchers conducted a randomized controlled study to determine whether acupuncture relieves migraine pain. Female patients were randomly assigned to one of the two groups: treatment or control. The treatment group received acupuncture specifically designed to treat migraines, while the control group received a placebo acupuncture. Twenty-four hours after patients received acupuncture, they were asked if they were pain-free. The results are shown below. | | Treatment | Control | Total | |------------|-----------|---------|-------| | **Pain** | 10 | 2 | 12 | | **No Pain**| 35 | 43 | 78 | **Questions:** a) What percentage of the treatment group experienced pain? 22% Round to the nearest whole percent. If a patient is selected at random, compute the probability of the following and **write the answer in decimal form** (round to **3 decimal places**): b) P(patient is pain-free) = 0.867 c) P(patient was in the treatment group) = 0.50

The image shows three probability questions related to medical study groups: d) P(Patient had pain or in the control group) = [Blank] e) P(Patient did not have pain or in the treatment group) = [Blank] f) P(Patient was in pain given they were in the control group) = 0.044 These questions are likely part of a lesson on probability and statistics, focusing on conditional probability and events in medical research contexts.
