The first digit can be any one of them ... 1, 2, 3, 4, 5 ... five choices. For each one . . .
The second digit can be any one of them ... five choices. For each one . . .
The third digit can be any one of them ... five choices. For each one . . .
The fourth digit can be either 2 or 4 ... two choices.
Total number of 4-digit possibilities: (5 x 5 x 5 x 2) = 250
To form a three-digit even number with different digits using the digits 0, 1, and 2, the last digit must be even, which can only be 0 or 2. If the last digit is 0, the first digit can be either 1 or 2 (2 options), and the middle digit will take the remaining digit (1 option). This gives us 2 valid numbers: 120 and 210. If the last digit is 2, the first digit can only be 1 (since it cannot be 0), and the middle digit must be 0. This gives us 1 valid number: 102. In total, there are 3 different three-digit even numbers: 120, 210, and 102.
None. There is 1 even digit but that is not the same thing.
To determine the number of even 2-digit whole numbers less than 50 using the digits 1-9, we need to consider the possible combinations. The even digits are 2, 4, 6, and 8. For the tens place, we can choose any digit from 1-4 (since we want numbers less than 50). For the units place, we can choose any of the even digits. Therefore, there are 4 choices for the tens place and 4 choices for the units place, resulting in a total of 4 x 4 = 16 even 2-digit whole numbers less than 50 using the digits 1-9.

Using the eight digits, 1 - 8 ,-- There are 40,320 eight-digit permutations.-- There is 1 eight-digit combination.
None. There is 1 even digit but that is not the same thing.
8 of them.
24 = 4*3*2*1 of them
There are 840 4-digit combinations without repeating any digit in the combinations.
To determine the number of even 2-digit whole numbers less than 50 using the digits 1-9, we need to consider the possible combinations. The even digits are 2, 4, 6, and 8.

The answer is 3*3*2*1 = 18. If the leading digit is 0 it is not a 4-digit number.
Answer: 2The values are 0 or 1.
