I think the answer is 33% probability of rolling a number less than 3. Or 2/6 probability if you are looking for a fraction. Probability is always the how many over the total. In a die there are 6 chances. And to get less than 3 is only 2 chances. So the fraction is 2/6. Now if you want to find the percent you would have to divide 2 by 6. That will get you 0.333. If you round and make it into a percent that would be 33%. Hope this helps!
