.
The number of all possible ordered triples (President; Vice-President; Secretary) of ten peoples is 10*9*8 = 720.


It is the full space of events.


The number of favorable triples (Tony as President; Luci as Vice-President; Secretary) is only 8,

since only 8 opportunities/people remain for the Secretary position.


Therefore, the probability under the question is  P = 8%2F720 = 1%2F90.    ANSWER

Solved.
