Asked in Math and Arithmetic How many 6 digits numbers can be formed from the digit and 9 which are divisible by 10 and no digit is repeated?I have been studying for a state test and am revieing many different types of questions and some I forget how to set up.

I can derive the answer to this, but I need for someone to show me how to set up a good equation to use. If there are just two digits, you have 5 choices for the first digit and then 4 choices without repetition for the next digit.

There are five different digits from which to choose. You are forming two digit numbers, that is a digit in the tens place, and a digit in the ones place. If you choose any of the five digits for the tens place there are four remaining choices for the ones place, because there are no repetitions allowed. Questions of this kind show up frequently on state exams, but they often differ as to whether they allow repetitions.

Operation 2: Pick the second digit: There are 4 ways to do this because you can't choose the same digit as from OP1.

This is also a permutation of 5 things, 2 at a time 5! All 3-digit numbers have a ones and a tens digit, so it is the comparable answer: sixty 4.

I solved it this way because if a number needs to be formed with a certain number of digits with no restrictions - which I think 'as often as desired' meansyou assign a scale to the given constituent digits and then pick the same number of digits as the new number needs, going from highest to lowest.

Then multiply these digits by each other to give the amount of different numbers that could be created. The next part of the question was finding how many 3-digit numbers can be formed using 2, 3, 4 and 5 using at most one each. I was able to get this question, by changing 2, 3, 4 and 5 to 1, 2, 3 and 4; then multiplying 4 by 3 by 2 to give 24 possibilities. Sign up to join this community.

Selenium crystals highHow do we solve this? Let's build a tree to answer it. We are going to be building sets of 3 numbers. Start with 1 and build. That's our first tree. See how it works? Starting with 1, we built looking at each possibility in turn from the right. We made our changes starting at the right and moving to the left, back to the place where our 1 was. See that? That's 25 combinations of 3 digits from a replacement set of 5 digits beginning with 1.
