how to find how many different combinations?
3247
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.

The number of 5-digit combinations is 10 5=100,000. So, one more than 99,999. You can generalize that: the number of N-digit combinations is 10 N.

6 x 5 x 4 x 3 = 360 possible combinations. Given a 4 digit integer. each digit can be 1 through 6. No two digits the same.

We conclude that there are 35−3×25+3=150 combinations. If there were no restrictions, the number of five digit codes that could be formed with the digits 1, 2, 3 would be 35 since there are three ways to choose each of the five digits.

Answer: There are 9,999 different combinations in a 4-digit lock. And now we have 1,000+9,000=10,000 combinations total. But…

Where 1,2,3 are the possible options and 3 is the number of repetitions. This will give an array of the 27 different combinations you can achieve.

So there are possible numbers of length 4. It's easy. The first digit can be 1,2,3,4,5 or 6 (6 combinations). We choose the second,third and fourth digit the same way we did it with the first (so it's 6*6*6 combinations) and the final answer is 6*6*6*6=1296 combinations.

Before calculating the odds for the different prize levels, calculate the total number of combinations possible for each portion of the PowerBall draw. Thus, there are 11,238,513 different ways in which 5 numbers can be chosen from a total of 69 unique numbers.

With three columns, each with ten possibilities, the number of total combinations is 10 × 10 × 10, or 1000. With three switches, each with two possibilities, the number of total combinations is 2 × 2 × 2, or 8.

There are about 1,000 combinations possible for a 3-digit number/code. There are 10,000 combinations possible for a 4-digit number/code.

It also means that when we selected one item (four choices), we created four different combinations with three items. Now we now all of the combinations and can add them up: 1 + 4 + 6 + 1 + 4 = 16 different possibilities.

Remember, the formula to calculate combinations is nCr = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time.

Remember, the formula to calculate combinations is nCr = n! / r! * (n - r)!, where n represents the number of items, and r represents the number of items being chosen at a time. Let's look at an example of how to calculate a combination. There are ten new movies out to rent this week on DVD.

It's the same as possibilities to a 6 digit code with known numbers and no repeats. With 1 item there are 6 possibilities with 2 you only have 5 choices after the first if you don't repeat the same item. So for 6 items the equation is as follows 6*5*4*3*2= 720 possible combinations of 6 items.
