How many possible combinations can be made from 10 items?

To calculate the number of possible combinations from 10 items, you can use the formula for combinations, which is nCr = n! / r!(n-r)!. In this case, n is the total number of items (10) and r is the number of items you are choosing in each combination (which can range from 1 to 10). So, if you are considering all possible combinations (r=1 to 10), the total number of combinations would be 2^10, which is 1024.


How many different combinations of 4 are possible from 6 items?

If order doesn't matter, 15 combinations and if order does matter, 360 combinations are possible.


How many 4 number combinations are there in the numbers1 to 20?

To calculate the number of 4-number combinations from 1 to 20, we can use the formula for combinations, which is nCr = n! / (r!(n-r)!), where n is the total number of items and r is the number of items to choose. In this case, n = 20 and r = 4. Plugging these values into the formula, we get 20C4 = 20! / (4!(20-4)!) = 4845. Therefore, there are 4845 different 4-number combinations possible from the numbers 1 to 20.

How many 12 number combinations are their using numbers 1-36?

To calculate the number of 12-number combinations using numbers 1-36, we can use the formula for combinations: nCr = n! / r!(n-r)!, where n is the total number of items to choose from (36) and r is the number of items to choose (12). Plugging in the values, we get 36C12 = 36! / 12!(36-12)! = 36! / 12!24! = (363534*...25) / (121110...*1). This simplifies to 125,736,770 unique combinations.


What lets you put equal groups together?

Combining equal groups together is possible through the concept of multiplication. By multiplying the number of groups with the number of items in each group, you can determine the total number of items. For instance, if you have 3 groups with 4 items in each group, you can put them together by multiplying 3 x 4 to get a total of 12 items.
