How many three digit or four digit even numbers can be formed from the set (23567)?
To form three-digit even numbers from the set {2, 3, 5, 6, 7}, we can use the digits 2 or 6 as the last digit (to ensure the number is even). For each case, we can choose the first two digits from the remaining four digits. For three-digit numbers, there are 2 options for the last digit and (4 \times 3 = 12) combinations for the first two digits, resulting in (2 \times 12 = 24) even numbers. For four-digit even numbers, we again have 2 options for the last digit. The first three digits can be selected from the remaining four digits, giving us (4 \times 3 \times 2 = 24) combinations for each last digit. Thus, there are (2 \times 24 = 48) even four-digit numbers. In total, there are (24 + 48 = 72) three-digit and four-digit even numbers that can be formed from the set.

How many three digit numbers can be formed out of 1234 if a digit can not be repeated?
Any 3 out of 4 = 4. Each set can be arranged 6 ways so 24 different numbers.

What are the 45 three digit numbers that have a sum of 9?
If the digit '1' occupies the hundreds place then the other two digits total 8. 108, 117, 126, 135, 144, 153, 162, 171, 180 (9 three digit numbers) Similarly with '2 in the hundreds position the the remaining digits total 7. 207, 216, 225, 234, 243, 252, 261, 270 (8 three digit numbers) When the remaining numbers 3 to 9 are set as the lead digit then the number of three digit numbers formed decreases by one each time. The final total of such numbers is, 9 + 8 + 7 + 6 + 5 + 4 + 3 + 2 + 1 = 45.

How many 2-digit numbers are there in the set of natural numbers?
There are 90 two-digit numbers in the set of natural numbers. These numbers range from 10 to 99, inclusive. To find the total, you can subtract the smallest two-digit number (10) from the largest (99) and add one: (99 - 10 + 1 = 90).
What does range in math problems?
Range is the greatest of a set of numbers-the least of a set of numbers.
How many 2-digit or 3-digit numbers can be formed using the digits 134568 and 9 which are diisible by 4?
48. Assuming no digit can be used more than once, the two digit numbers divisible by 4 are: 16, 36, 48, 56, 64, 68, 84, 96 8 of them. For any number to be divisible by 4, only the last two digits need be divisible by 4; so for three digit numbers, each of the two digit numbers above can be preceded by any of the remaining 5 digits and still be divisible by 4. → 5 x 8 = 40 three digit numbers are divisible by 4 → 40 + 8 = 48 two or three digit numbers made up of the digits {1, 3, 4, 5, 6, 8, 9} are divisible by 4. If repeats are allowed, there are an extra 2 two digit numbers (44 and 88) and each of the two digit numbers can be preceded by any of the 7 digits, making a total of 7 x 10 + 10 = 80 two and three digits numbers divisible by 4 make up of digits from the given set.
How many 3 digit numbers can be formed from the digits 0 through 9 in a set of three?
If the digits can be used more than once, then 900. If not, then 648.
