zack is a physical therapist who specializes in pediatric leg injuries. his patients differ in age and type of injury. what is the probability that a randomly selected patient suffers from knee pain given that the patient is 20 - 45 years old? simplify any fractions.

Answer

Explanation:

Step1: Calcular el total de pacientes de 20 - 45 años

Sumamos los pacientes de 20 - 45 años con dolor de rodilla y tobillo. $10 + 7=17$.

Step2: Calcular la probabilidad

La probabilidad de que un paciente de 20 - 45 años tenga dolor de rodilla se calcula dividiendo el número de pacientes de 20 - 45 años con dolor de rodilla entre el total de pacientes de 20 - 45 años. La fórmula de probabilidad condicional $P(A|B)=\frac{n(A\cap B)}{n(B)}$. Aquí, $A$ es el evento de tener dolor de rodilla y $B$ es el evento de ser de 20 - 45 años. Entonces $P=\frac{10}{17}$.

Answer:

$\frac{10}{17}$
