Answers:
(a) 60%
(b) 0%
Explanation
(a) 40% of the Volvos are red, so the remaining 100% - 40% = 60% of the Volvos must be some color other than red.
(b) I'm assuming that Ford does not own Volvo, or vice versa. I'm assuming they are separate companies. I'm also assuming that the two companies have not formed a partnership of some kind. If so then there's a 0% chance of getting a Ford because the entire lot consists of Volvos or Volvo related brands.

The way the problem is stated, it is impossible to answer part a.
For part b, it is specified that all the vehicles in the lot are Volvos, so that question is easy to answer.
But for part a, it is not specified that all the vehicles are Volvos.
So for part a, there can apparently be vehicles at the dealership that are not Volvos -- and the probability of picking a non-red Volvo depends on the number of vehicles that are not Volvos.
Since we don't have that information, the question can't be answered.
