Digit 1 = 10 choices (0,1,2,3,4,5,6,7,8,9)

Digit 2 = 10 choices (0,1,2,3,4,5,6,7,8,9)

Digit 3 = 10 choices (0,1,2,3,4,5,6,7,8,9)

Digit 4 = 10 choices (0,1,2,3,4,5,6,7,8,9)

Number of combinations = 10 x 10 x 10 x 10 = 104 =10000

How many ways can you combine 2 digits?

To combine 2 digits, you can choose from the 10 digits available (0-9). If repetition is allowed, there are (10 \times 10 = 100) combinations. If repetition is not allowed, there are (10 \times 9 = 90) combinations, as you select the first digit and then choose a different second digit.


Is the subset H of 0 1 consisting of all decimals that are 100 digits long infinite or finite?

It's finite (although very big). If a decimal between 0 and 1 is exactly 100 digits long, then there are 10 ways to choose the first digit, 10 ways to choose the second, and so on. This gives us 10100 ways to choose all 100 digits, which is very large (it's a googol, in fact) but not infinite.


How many ways can you make a number with 0-9?

9


Given the digits 0-9... how many ways can you form an even number without replacement of numbers?

one digit: 5 ways two digits: 5 * 9 ways three digits: 5 * 9 * 8 ways four digits: 5 * 9 * 8 * 7 ways ... ten digits: 5 * 9! ways So if you have to use ten digits, then the answer is 5 * 9! = 1814400. If you can use anywhere from one to ten digits, then the answer is: 5 * (9! + 8! + 7! + 6! + 5! + 4! + 3! + 2! + 1) = 2045565
