Since there 100 numbers in total and 10 numbers that are "successful", 10/100=1/10 is the answer.

Count how many integers are in that range, which is 20-10+1=11. Now divide that by the total number of choices, which is 99-0+1=100. So, your answer would be 11/100, if I'm not mistaken.

You know, I think you are just giving your hw to us. That is cheating, you know. You are really not learning and you have to try to solve them first! Most of these problems have a similar structure, so you should maybe ask for 2 questions and try to do the rest yourself after reading the explanations. That is how you really learn.
