How many 5 digit even numbers with distinct digits can be formed?
Answer & Solution The 5 digit even numbers can be formed out of 1, 2, 5, 5, 4 by using either 2 or 4 in the unit’s place. This can be done in 2 ways. Corresponding to each such arrangement, the remaining 4 places can be filled up by any of the remaining four digits in 4! / 2! = 12 ways.

How do you find distinct numbers?
Algorithm to print distinct numbers in an array
- Declare and input the array elements.
- Traverse the array from the beginning.
- Check if the current element is found in the array again.
- If it is found, then do not print that element.
- Else, print that element and continue.
How many distinct-4-digits don’t include a 0?
If the last 4 don’t include 0, you only have 5 choices left for the first one. Since the number of distinct-4-digits arrangements which don’t include a 0 is 9 C 4 × 4!, the calculation gives which simplifies to 9 × 8 × 7 × ( 30 + 60 − 36), i.e. 9 x 9 x 8 x 7 x 6, as before.
How many 5-digit numbers are there in strictly descending order?
The resulting 5 digit numbers are all possible 5-digit numbers in descending order. Therefore, there are [10!/ (5!5!)] = 252 5-digit numbers in strictly descending order.
How many choices are there for each digit in the number system?
There are 9 choices for the first digit, since 0 can’t be used. For the second digit, you can use any of the remaining 9 digits. For the third digit you can use any of the 8 digits not already used. For the next digit, there are 7 choices. And for the final digit there are 6 choices left.
Can a zero appear in a 3-digit number?
If we eliminate the possibility of a number beginning with a zero, then — since all following digits must be bigger — the digit zero cannot appear in any of the 3-digit numbers. We also assume that no digit can appear more than once in a 3-digit number.
