Suppose you have already had a disease, D, and doctors tell you that you cannot contract it again. Assuming the doctors are correct, which of the following probability statements about your contracting the disease is correct, where P(D) stands for the probability of contracting the disease? (Hint: A probability is a value between 0 and 1, where 0 means that the event will not occur with certainty and 1 means the event will occur, with certainty.)
 A. P(D) = 0
  B. P(D) = 1
  C. 0   D. P(D) = 0.5

Question 2

Suppose a student has had one illness in the last month, but her roommate has had two. With no other information about this student or her roommate, given the information in this video, what is your best guess about the student's and her roommate's hand-washing habits?
 A. The student does the best job of washing her hands.
  B. The student's roommate does the best job of washing her hands.

Answer to Question 1

A. P(D) = 0

FEEDBACK:
If you cannot, with certainty, contract the disease, then the probability of your contracting that disease is 0.

Answer to Question 2

C. All of the above.

FEEDBACK:
Your best guess should be the answer that you think is most likely. That is, the event with the higher probability. A probability describes the likelihood of an event occurring given all the information known about the event. In this case, all you know is that one student had one more illness than the other. The video actually says that washing hands prevents your catching a bug but later, when it discusses transmission of disease, it's not clear whether the benefit of hand-washing is to prevent you from getting sick, prevent you from getting someone else sick, or both. Since these students are roommates, either of these answers can constitute a best guess.

For example, you may believe that the person who does the worse job of washing her hands is the one who has more illnesses. Alternatively, you may believe that perhaps each student contracted a different illness outside of their shared room. Then, the student who did a worse job of washing her hands transferred her illness to her roommate, while the other one did not. That would mean, in this case, that the student who does the worse job and hand-washing has the fewest illnesses
