Question

addison is a physical therapist who specializes in pediatric leg injuries. her patients differ in age and type of injury. what is the probability that a randomly selected patient is not 13 - 19 years old and does not suffer from ankle pain? simplify any fractions.

Explanation:

Step1: Calculate total number of patients

Add all the values in the table: \(3 + 6+4 + 5=18\)

Step2: Find number of patients who are not 13 - 19 and not with ankle pain

Patients who are not 13 - 19 (i.e., 0 - 12) and not with ankle pain (i.e., with knee pain). The value is \(3\)

Step3: Calculate the probability

Probability \(P=\frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}\). So \(P = \frac{3}{18}=\frac{1}{6}\)

Answer:

\(\frac{1}{6}\)
