Ashley and Vinny 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 Vinny will be chosen? Choose the correct answer
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 Vinny have to be chosen, the remaining selection is 3 people from 8.   8C3/10C5= 2/9. Option 2/9.
