After the spa drawing there are 19 people in the pool for the baseball tickets ( the one is the spa winner).
So the employee would have a 1/19 chance of winning the baseball tickets.
This is a dependent probability or conditional event.

The probability will be 1/19
Because one employee was already drawn at the spa day.
