Mariah has decided to hire three workers

Mariah has decided to hire three workers. To determine whom she will hire, she has selected a group of 12 candidates. She plans to have one working interview with 3 of the 12 candidates every day to see how well they work together. How many days will it take her to have working interviews with all the different combinations of job candidates?

This problem repeats another one in the library (at most with different numbers), so it's left out of browsing.
