How many even numbers of 4 different digits each can be formed form digits 3 5 6 7 and 9 How many odd numbers?

We keep 6 as the last digit (unit digit) and fill the thousands, hundreds and tens places with the remaining digits. The filling up of these places can be done in 4P3 ways = 4(3)(2) = 24 ways. So total number of even numbers of 4 different digits that can be formed out of 3,5,6,7 and 9 is 24.

How many 4-digit even numbers can be formed using 1 3 7 8 only once?

You can form 24 numbers. ‘9’ 4-digit even numbers can be formed by using the digits 1, 3, 7, and 8 only once.

How many 4-digit even numbers can you make with 4 numbers?

If the 4th digit is 0, then that leaves 5 possible numbers for the 1st digit, 4 for the 2nd, and 3 for the 3rd. 5 x 4 x 3 = 60 possible 4-digit even numbers. If the 4th digit is 2 or 6, that leaves 4 possible numbers for the 1st digit (can’t be 0), 4 for the 2nd digit, and 3 for the 3rd digit. 4 x 4 x 3 x 2 = 96 possible 4-digit even numbers.

Does the Order of the numbers matter in a 5P3 game?

The order matters, and there are no repeats, so it’s a permutation: If the first digit cannot be zero then we have 5P3 results where 0 is the last digit and all other numbers are in play. We have two cases (last digit = 2 or 6) where only 4 numbers play in the first position with 4P2 choices in between.

How do you make a number even?

In order for it to be even, it needs to end in an even digit. This means one of 0, 2, and 6. We will consider two cases: 0 is used and 0 isn’t used. The reason 0 gets a separate case is because it can’t be a starting digit, so there’s one more option for the first digit if we use 0 for one of the other digits.

What is the number of even numbers that start with 0?

If we assume that the first digit is 0, we now have 3 remaining spots. The units digit has 2 options, 2 and 6, the tens has 4 options, and the hundreds has 3, giving us 2 ∗ 4 ∗ 3 = 24. These are the even ones starting with 0.
