350-101+1 = 250

299-200+1 = 100

Probability = 100/250 = 2/5

Ans: "A"

Shouldn't the number of tickets with 2 in hundred's digit be 100 - from 200 to 299? Hence, 100 favorable outcomes out of a possible 250 outcomes and hence probability is 100/250 = 2/5. I think answer should be 2/5 and hence A.

Reading this question reminded me of something that I like to tell my students:

"When you solve a question, don't just solve that question. Think what you would have done had the question been a little different. Apply as many different variations as you can and try to solve each. That will help you build concept."

e.g. they have made the question a little simpler by giving you that you need numbers with 2 in the hundred's place. What if the question asked for numbers with a 2 (in any place) or numbers with only one 2 (in any place) etc.

The more you analyze the problems, the better you will get at answering tougher questions.
