There are 100 three-digit numbers that have a hundreds digit of 2–all the numbers from 200 to 299, inclusive. The total number of three-digit integers is 900–all the numbers from 100 to 999, inclusive. Thus, there are 100 ”desired outcomes” and 900 ”possible outcomes,” resulting in a probability of: 100/900=1/9
