Answer

Answer:

$\frac{10}{17}$

Explanation:

Step1: Identify relevant values

For 20 - 45 years old, knee pain patients = 10, total patients = 10 + 7 = 17.

Step2: Calculate conditional probability

Probability = $\frac{\text{Number of knee - pain patients in 20 - 45 age group}}{\text{Total number of patients in 20 - 45 age group}}=\frac{10}{17}$
