The second digit can be 2,4,6, or 8. There are 4 ways of choosing the second digit. The first digit can be chosen from the remaining 8 digits. 8x4 = 32 numbers. Here, it is assumed that the numbers do not repeat
How many two digit numbers can be formed with the digits 0123456789 if repetition of digits are not allowed?
To form a two-digit number using the digits 0-9 without repetition, the first digit (the tens place) can be any digit from 1 to 9 (9 options), since a two-digit number cannot start with 0. The second digit (the units place) can then be any of the remaining 9 digits (including 0 but excluding the first digit). Therefore, the total number of two-digit numbers that can be formed is 9 (choices for the first digit) multiplied by 9 (choices for the second digit), resulting in 81 possible two-digit numbers.

120. There are 6 digits. If we pick the digits in order, there are 6 possible digits for the first digit 5 remaining digits for the second digit 4 remaining digits for the third digit. 6*5*4 = 120.
How many possible three-digit passwords can be formed using digits 0 through 9 if no digits are repeated?
Oh, what a happy little question! If we have 10 digits to choose from (0 through 9) and we can't repeat any, then for the first digit we have 10 options, for the second digit we have 9 options left, and for the third digit we have 8 options remaining. So, the total number of possible three-digit passwords would be 10 x 9 x 8 = 720. Isn't that just delightful?

How many three digit numbers can be formed using the digits 873 and 6 without repetition?
I take it that you want to make three digits numbers with 8,7,3, and 6 without repetition. The first digit cane be selected from among 4 digits, the second from 3 digits, the third digit from 2, hence the number of three digit numbers that can be formed without repetition is 4 x 3 x 2 = 24
