Conditional probability of choosing one of two clinics

95 Views Asked by At

Two competing clinics A and B treat one disease. After the treatment round in clinic A, 80% of patients recover. In clinic B, 70% of patients recover after one treatment round. Patients are directed for treatment by an insurance company to either clinic A or B, wherein clinic A is chosen twice as often as clinic B.

What's the probability that a client of the insurance company, who needs treatment will get to clinic A and recover after the treatment round?

I don't think I have solved this task correctly. Could you guide my thoughts to the right direction?). Below is my strange solution

P(R | A)=0.8 (After the treatment round in clinic A, 80% of patients recover)

P(R | B)=0.7 (In clinic B, 70% of patients recover after one treatment round)

P(A) = $\frac 23$ (clinic A is chosen twice as often as clinic B)

P(B) = $\frac 13$ (probability of choosing clinic B )

\begin{align} P(A \,|\, R) = \frac{P(R \,|\, A)\cdot P(A)}{P(A)} \end{align}

$$P(A | R) = \frac {0.8 \cdot 0.66}{0.66}$$

P(A | R) = P(R | A)???

What about this additional task?

Under the same conditions, What's the probability that a client of the insurance company, who needs treatment will get to clinic A and not recover after the treatment round?

Am I supposed to find $P(A \cap \overline R)$?

Then $P(R) = P(R \mid A)\cdot P(A)+P(R \mid B)\cdot P(B) = \frac 8 {15} + \frac 7 {30} = \frac {23} {30}$

$P(\overline R) = 1 - \frac {23} {30} = \frac {7} {30}$

$P(A \cap \overline R) = \frac {2} {3} \cdot \frac {7} {30} = \frac {14} {90} = \frac {7} {45}$
