Ashley and Vinie work on a sales staff with 8 other salespeople. If five members of the staff will be chosen at random to attend a sales workshop, what is the probability that both Ashley and Vinie will be chosen?  Select the correct option.
A) 1/10
B) 3/28
C) 2/9
D) 1/4
E) 1/2
I did slightly different and hence obviously ended up with the answer 2/9.   I assumed that because Ashley and Vinie have to be chosen, the remaining selection is 3 people from 8.   8C3/10C5= 2/9. Option 2/9.
