Question

How many times does the digit '6' appear between 6 and 100? ​

Answer 1

Step-by-step explanation:

Hence, there are total 1000*3 = 3000 digits from 100 to 999. We also know that each number in {0,1,2,3,4,5,6,7,8,9} has an equal chance of 1/10 to appear in the total 3000 digits, so number 6 appears in 3000*(1/10) = 300 times! Done!
