The patients were grouped in 4 categories: one for each drug, and a control group. The patients in the control group were not given any drug to treat the disease. The following table shows the results of the study:

1. If you know that the patient we selected was cured in less than three months, what is the probability that she was treated with drug 1?
2. What is the probability that the patient was treated with any of the drugs and was cured between 6 and 12 months from the start of the treatment?
