Zero. Only the digits 5 and 0 appear in 500.
95
1 digit number: only 1 number 2 digits number: 18 numbers 3 digits number: 76 So there are 95 numbers containing 9.
To find how many times the digit '9' appears between 1 and 500, we can count occurrences in each digit place (hundreds, tens, and units). In the range of 1 to 500, '9' appears in the units place 50 times (9, 19, 29, ..., 499) and in the tens place 40 times (90-99, 190-199, 290-299, 390-399). It does not appear in the hundreds place in this range. Therefore, the total count is 50 + 40 = 90.
The number 500 contains the digit 5 one time, specifically in the hundreds place. Therefore, there is one occurrence of the digit 5 in the number 500.
500 or so.

900
Instead of going from 1 to 500, let's just subtract one from the set and come up with "How many 3's appear from 1 to 499?" Total possible combinations in this, including leading zeros, is 5*10*10, i.e. 5 possible in the first set(0,1,2,3,4), and 10 in the second two(0,1,2,,4,5,6,7,8,9). Instead of figuring out how many have a 3, lets figure out how many don't. Well there is 4 possibilities in the first (0,1,2,4), and nine in the second two (0,1,2,4,5,6,7,8,9). So, total = 5 * 10 * 10 = 500 Without 3 = 4 * 9 * 9 = 324 500-324 = 176 There are 176 numbers from 1 to 500 that have the digit 3 in them.

To find how many times the digit '9' appears between 1 and 500, we can count occurrences in each digit place (hundreds, tens, and units). In the range of 1 to 500, '9' appears in the units place 50 times (9, 19, 29, ..., 499) and in the tens place 40 times (90-99, 190-199, 290-299, 390-399). It does not appear in the hundreds place in this range. Therefore, the total count is 50 + 40 = 90.
The 3 digit numbers under 500 are 100 through 499.
The number 500 contains the digit 5 one time, specifically in the hundreds place. Therefore, there is one occurrence of the digit 5 in the number 500.
500 or so.
