In a sample of flu patients, 89% are found to also have low-grade pneumonia. What are the ODDS of a flu patient having low-grade pneumonia?

Solution

P(low grade) = 0.89

P(no low grade) = 1 - 0.89 = 0.11

So, Odds that a patient has low grade pneumonia = P(low grade) / P(no low grade)

--> 0.89 / 0.11

89/11 --> ANSWER
