How many four digit numbers can be formed using the digits 2 3 5 1 7 9 repetition of digits is not allowed?

Explanation: The first digit of the 3-digits can take 7 distinct values: 1, 2, 3, 4, 5, 7, 9. As repetition is allowed, the second digit can also take 7 distinct values, and the third can take 7 distinct values aswell, giving a total of 7⋅7⋅7=343 distinct combinations of numbers.

How do you calculate the number of possible combinations?

Remember that combinations are a way to calculate the total outcomes of an event where order of the outcomes does not matter. To calculate combinations, we will use the formula nCr = n! / r! * (n – r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

How many permutations of 4 numbers are there?

256 permutationsIn the first position we have 4 number options, so like before place a “4” in the first blank. Since we are allowed to reuse numbers, we now have 4 number options available for the second digit, third digit, and fourth digit as well. By allowing numbers to be repeated, we end up with 256 permutations!

How can you find a divisibility by 4?

If any number ends in a two digit number that you know is divisible by 4 (e.g. 24, 04, 08, etc.), then the whole number will be divisible by 4 regardless of what is before the last two digits. Alternatively, one can simply divide the number by 2, and then check the result to find if it is divisible by 2.
