Answer 2

The number 3 occurs once, with no repetitions.

If you’re asking how many times the digit 3 appears in the decimal (base 10) representation of the numbers from 1 to 100, we can count them as follows. There are ten numbers that end in 3, namely: 3, 13, 23, 33, …, 93. There are 10 two-digit numbers that start with 3, namely: 30, 31, 32, 33, …, 39. Thus, the digit 3 occurs 20 times. (Note that we’ve counted 33 twice, since it occurs in both lists. That’s okay, because it has two 3s and so should be counted twice.)

Finally, if you want to know how many of the numbers from 1 to 100 have a 3 in their decimal representation, the answer is 19, since now we only want to count 33 once.
