The patient was a 5-year old male who awoke on the day prior to evaluation with a sore throat and fever. His mother treated him symptomatically with Tylenol, and he stayed home. That night, he slept well, but the next day he awoke still complaining of sore throat and fever, as well as headache and abdominal pain. On physical examination, he had a fever, and his anterior pharynx and tonsils were red. His anterior cervical lymph nodes at the angle of the mandible were enlarged and tender. No skin lesions or rashes were seen. He did not have a cough, runny nose, or conjunctivitis. A rapid antigen test for Group A streptococci (GAS) was taken, and the results were positive. As a result, the clinician prescribed a 10-day course of oral amoxicillin.

It’s the year 1995 and John Smith is staying overnight at a hotel before an important meeting the next morning. He asked the customer service desk to give him a 7 am wake-up call. The probability that he gets the call is 0.9. If he gets the call, the probability that he will arrive for the meeting on time is 0.9. If the call is not given, the probability that he will be on time for the meeting is 0.4.
a) Calculate the probability that John Smith will not arrive on time for the meeting.
b) If John Smith is on time for the meeting, what is the probability that the wake-up call was not made?
