What digit is the most frequent between the numbers 1 and 1,000 (inclusive)?

What digit is the least frequent between the numbers 1 and 1,000?

To solve this riddle you don’t want to manually do all of the math but rather try to figure out a pattern.

I would guess ‘1’ is most frequent and ‘0’ is least frequent.

I’m guessing there is only one more ‘1’ than there are most other digits (because 1000 is the only 4-digit number, and it has a 1 in it), but there may be a few less 0’s (because no number starts with a 0).

Brent, you are today’s winner and it is good to see you are having fun with the Math riddles.

The most common digit is ‘1.’ 0 is the least common digit even though 1,000 has three zero’s ! The digits 0 through 9 all follow the same pattern there is exactly 1 occurrence of each digit for every ten numbers. For instance the digit 2 appears once between 10 and 19, at 12. And 2 appears once between, 30 and 39 at 32. However, each of the digits 1 through 9 also appear in other numbers in the tens and hundreds place. So to figure out how to answer the first riddle you had to see what distinguishes the number 1? Only that we are including 1,000 which would be the first ‘1’ in a new series of ten! In other words, the digit 1 only has a single extra occurrence (301 occurrences) compared to 2 or 3 or 9 which each have exactly 300 occurrences. The reason that zero has the least (BY FAR at only 192 occurrences) is because zero does not have any equivalents to 22, 33, 44, 222, 3333 etc..1

The most used number between 1 and 1,000 is 1, on the contrary, the least used number is 0.

0

1 most

0 less

0 and 9

0 because there are 3 0s in 1 and 1000, but only 2 1s

0 is the least frequent, 1 is the most frequent

my guess is 1-9 have 300 and 0 has 192

First question: 0

Second Question: 2

I would guess that 1 is the most frequent digit and 0 is the least frequent digit.

most frequent – 1

least frequent – 0

I think all the numbers will have equal frequency.

The question is what number is most frequent BETWEEN 1 and 1000, so 1 and 1000 are not included. That would mean no numbers are more frequent, only 0 is the most infrequent.
