One card selected randomly from deck. Find odds against drawing a spade greater than 2 and less than 9
What the other tutors gave was probability. Odds for an event is defined as the ratio of the probability for the event to the probability against it.
In your case, the event E consists of picking one of the six cards 3S, 4S, 5S, 6S, 7S, 8S (S = Spades).
There are 6 ways for E to happen, and 46 ways for it not to happen. so the odds against E is
46:6 = 23:3
