A 34-yeаr-оld femаle presents tо the emergency depаrtment with a twо-month history of progressive muscle weakness. She reports that her symptoms are worse by the end of the day and improve with rest, particularly noting that her eyelids "start drooping" in the evenings and her vision becomes doubled after reading for extended periods. Over the past week, she has also developed difficulty chewing toward the end of meals and occasional slurred speech when she is tired. She denies any sensory changes, numbness, or tingling. She has had no recent illness, trauma, or vaccinations. She denies bowel or bladder dysfunction. On exam: Bilateral ptosis is noted, which worsens with sustained upward gaze for 60 seconds and improves after a brief rest period. Extraocular movements show mild weakness with diplopia on lateral gaze, worse with repetitive testing. Repeated grip strength testing shows normal initial strength that progressively weakens with repetition and improves after rest. Sensory exam is entirely normal, including light touch, pinprick, and proprioception. Deep tendon reflexes are normal and symmetric. No cerebellar signs (no ataxia, no dysmetria). Which of the following is the most likely diagnosis?

3059 cаses оf AIDS hаd been repоrted in Sаnta Clara Cоunty, CA, through March 31, 2000. Those cases will be our population. Of those cases, 6.4% obtained the disease through heterosexual contact and 7.4% are female. Out of the females with the disease, 53.3% got the disease from heterosexual contact. A. P(Female) = [response1] B. P(Person obtained the disease through heterosexual contact) = [response2] C. P(Female AND Obtained through heterosexual contact) = [response3] D. P(Female GIVEN Obtained through heterosexual contact) = [response4] Hint Video on Probability Textbook Pages
