Calculating the frequency of the number 3 in the numbers from 1 to 100
To determine how many times the number 3 appears in the numbers from 1 to 100, we need to analyze the pattern and frequency of the digit 3 in each number.
Numbers with a single occurrence of the digit 3
- The numbers 3, 13, 23, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39 all contain the digit 3 once.
- There are 13 numbers with a single occurrence of the digit 3.
Numbers with multiple occurrences of the digit 3
- The numbers 33, 43, 53, 63, 73, 83, 93 contain the digit 3 twice.
- There are 7 numbers with two occurrences of the digit 3.
Calculating the total frequency of the digit 3
- Adding up the single occurrences and the multiple occurrences of the digit 3, we get a total of 20 occurrences of the digit 3 in the numbers from 1 to 100.
Therefore, the correct answer is option 'C', 20 times.
