How many even 3-digit numbers can be formed from the digits 1 2 3 and 5 if each digit can be used only once?
The final digit must be a 2 to form an even number. The first digit may be any of three remaining digits (1, 3, 5) while the second digit may be any of the two remaining digits. All together, that makes 3*2 = 6 distinct even numbers.
How many 3 digits numbers can be formed from numbers 3 7?
there cant be any numbers fromed becuase you only have 2 numbers if u wanted to be more comlicated u cud go into decimals
How many combinations of numbers can you get with 1189 with one repeating?

How many 3-digit numbers can made using the digits 2 3 4?
If you can repeat a digit, there are 27. If you can't repeat a digit, there are only 6.
How many three digits numbers contain only 5 and 6?
The only numbers that can be made with ONLY 5 and 6 are 56 and 65. That is because 5 and 6 are only 2 numbers. If you wanted a three digit number, you would have to use double of one number. You could say these numbers: 556 566 565 656 665 Other than that, I do not know.

18
What is 3 digits plus 3 digits and equals 3 digits only using numbers 1 through 9 without carrying a number?
There is no solution to this problem. If each digit can be used once only then we have 5 odd numbered digits (1,3,5,7,9) and 4 even numbered digits (2,4,6,8). To create the two numbers that are added together requires the following combinations of digits. 5 Odd & 1 Even ....when added these will generate 2 Even digits & 1 Odd digit but the remaining digits are 3 Even. 4 Odd & 2 Even. These will generate 3 Even digits OR 1 Even digit & 2 Odd digits but the remaining digits are 1 Odd & 2 Even. 3 Odd & 3 Even. These generate 3 Odd digits OR 2 Even & 1 Odd digits but the remaining digits are 2 Odd & 1 Even. 2 Odd & 4 Even. These generate 3 Even digits OR 2 Odd & 1 Even digits but the remaining digits are 3 Odd & no Even.

An n-digit number has 4^n such numbers.
How many digits are in 1 through 39?
There are an infinite number of them. But if you only count the whole numbers, then there are only 69 of them.
Which numbers have two even digits?
There are 20, 2-digit integers that have both of there digits as even: 20, 22, 24, 26, 28, 40, 42, 44, 46, 48, 60, 62, 64, 66, 68, 80, 82, 84, 86, 88. If you lift the constraint of the number itself only being able to have 2 digits, then there are an infinite amount of numbers with 2 even digits in them, as you can string together two of the following numbers, 0, 2, 4, 6, and 8, with as many odd numbers as you wish. Finally, to answer your question in the discussion section, there are an infinite number of even numbers. This is because there are an infinite number of integers, and 2 X any integer is necessarily even.
