To calculate the probability that a randomly selected employee is a physiotherapist, we need to use the following probability formula:

\[
P(\text{physiotherapist}) = \frac{\text{Number of physiotherapists}}{\text{Total number of people}}
\]

From the table:

- The total number of physiotherapists is 20.
- The total number of people is 56.

Thus, the probability is:

\[
P(\text{physiotherapist}) = \frac{20}{56} = \frac{5}{14}
\]

Therefore, the probability that a randomly selected employee is a physiotherapist is \( \frac{5}{14} \).
