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.
How do you make a 4 digit odd number?
To make a 4 digit odd number you have restriction on the digit at ones place and at the thousandth place so you are free to use any number at the other 2 places provided you use the number only once. There is also a bit of complication as discussed below…
How many odd permutations of 4 numbers are there?
There are 4! = 24 permutations of the 4 digits. Half of them end in 0 or 2, so only 12 of them are odd. Since a four-digit number can’t start with 0 we must exclude the permutations that start with 0. Once we fix the last digit, there are three digits left, and one of them is 0, so we exclude one third of the 12 cases.
How many options are there if 0 is not the unit digit?
If 0 is not the units digit, we have 2 options, either it is tens or hundreds. In each of those cases, the units digit is 2 or 6, which is 2 options again, and the remaining two digits give us 4 and 3 options, for a total of 2 ∗ 2 ∗ 4 ∗ 3 = 48 options.
