I think you typed the question wrong or something

12. completeidiot Group Title

its fine, a standard number cube has 6 sides, 1,2,3,4,5,6 less than 3 would be 1,2

13. completeidiot Group Title

lets just call it a dice...

14. miadeex Group Title

nope thats what the book says

15. AccessDenied Group Title

$\text{Odds of an event} = \frac{\text{# of favorable outcomes}}{\text{# of unfavorable outcomes}}$ Not to be confused with probability of an event.

16. completeidiot Group Title

anyways you are correct

17. AccessDenied Group Title

So basically, we just find: # of favorable outcomes (we roll a # less than 3: a 1 or a 2.) There are 2 here. # of unfavorable outcomes (we roll something else: 3, 4, 5, or 6.) There are 4 here. These two quantities should add up to the total # of possible outcomes. Then take the fraction of the # of the favorable outcomes over the # of unfavorable outcomes. 2/4. Simplify as necessary.
