0.6957 = 69.57% probability that you are randomly assigned a General Practitioner or a doctor under the age of 50.

Step-by-step explanation:

I am going to solve this question treating these events as Venn events.

I am going to say that:

Event A: General practitioner.

Event B: Under the age of 50.

Suppose that 9 out of the 23 doctors in a small hospital are General Practitioners

This means that $P(A) = \frac{9}{23}$

10 out of the 23 are under the age of 50

This means that $P(B) = \frac{10}{23}$

3 are both General Practitioners and under the age of 50.

This means that $P(A \cap B) = \frac{3}{23}$

What is the probability that you are randomly assigned a General Practitioner or a doctor under the age of 50?

This is:

$P(A \cup B) = P(A) + P(B) - P(A \cap B)$

Considering the values we have for this exercise.

$P(A \cup B) = \frac{9}{23} + \frac{10}{23} - \frac{3}{23} = \frac{9+10-3}{23} = \frac{16}{23} = 0.6957$

0.6957 = 69.57% probability that you are randomly assigned a General Practitioner or a doctor under the age of 50.
