the probability it will not be toyota is therefore 12 / 17.
this means the probability it will be toyota is 5 / 17.

the odds against ford are 8 to 3.

about the simplest explanation of odds and probabilities can be found here:

let s = number of successes.
let f = number of failures.

probability of success = s / (s+f)

probability of failure = f / (s+f)

odds in favor of success = s / f

odds against success = f / s
