Jack and Jill work at a hospital with 7 other workers

Jack and Jill work at a hospital with 7 other workers. For an internal review, 2 of the 9 workers will be randomly chosen to be interviewed. What is the probability that Jack and Jill will both be chosen?

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