Suppose you want to estimate the probability that a patient will develop an infection while hospitalized at a particular hospital. In the past year, this hospital had 8,650 patients, and 812 of them developed an infection. What is the estimated probability that a patient at this hospital will develop an infection?
1. P(the patient develops an infection) = 1/812
2. P(the patient develops an infection) = 1/8,650
3. P(the patient develops an infection) = 812/8,650
4. P(the patient develops an infection) = 5,738/8,650
5. P(the patient develops an infection) = 812/5,738
