How many different 3 digit numbers can be formed by using the digit 1 2 and 3 when repetition is allowed?

Answer: 125 As repetition is allowed, So the number of digits available for B and C will also be 5 (each). Thus, The total number of 3-digit numbers that can be formed = 5 × 5 × 5 = 125.

How many three digit numbers can be formed using all of the digits 1/2 and 3 exactly once 1 point?

Similarly, when unit digit is 4, the number of possible words in 12. So total possible words = 24. With only three digits in the final number, and only one or two of each digit to choose from, the final number will have three different digits, or two digits repeated and one different digit.

How many 3 digit codes can be generated using only even numbers?

For each of these ways, y can be chosen in 8 ways. Hence, the desired number is 41 × 8 = 328 numbers 3-digit even numbers exist with no repetitions. Units digit can be among 0,2,4,6,8. There are some good answers here.

How many three digit numbers can be generated using the digits 1,2 3 4 without repeating any digit?

There are only two numbers left and the units place can be filled in 2 ways. Hence by fundamental counting principle, the total number of three digit numbers = 4 x 3 x 2 = 24.

How many 3 digit numbers can be formed using the digits 0?

Originally Answered: How many 3 digit numbers can be formed using the digits 0, 1, 2, 3, 4, 5, 6, 7, 8, 9 if repetitions of digits are not allowed? There are nine possible first digits, because numbers beginning in 0 drop the 0, so 012 is really just 12, a two digit number. The first digit must be 1 thru 9, nine possible digits.
