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

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

    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.
