What is a finding all possibilities problem?
It encourages children to persevere and try different approaches if one approach does not work. Many of the problems are easily extendable by simply changing one of the variables. The aim of the problems is to get kids thinking logically and working systematically to find all the possible answers.
How do you find all possibilities?
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 do you generate all possible combinations of one list?
To create the list of all possible combinations:
- Click the Expand button in the column header. From the sub-menu: Select only the column with the data we wish to retain (i.e., in our example, uncheck the Temp column)
- The list of possible combinations now appears in the Power Query window.
How do you find all possible combinations without repetition?
The number of k-element combinations of n objects, without repetition is Cn,k = (n k ) = n! k!( n − k)! . The counting problem is the same as the number of ways of putting k identical balls into n distinct boxes, such that each box receives at most one ball.
What is the focus of combination?
A combination focuses on the selection of objects without regard to the order in which they are selected. A permutation, in contrast, focuses on the arrangement of objects with regard to the order in which they are arranged.
How do you explain a combination?
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter. In combinations, you can select the items in any order. Combinations can be confused with permutations.

How do you find all permutations of an array?
You take first element of an array (k=0) and exchange it with any element (i) of the array. Then you recursively apply permutation on array starting with second element. This way you get all permutations starting with i-th element.
How do you help children to find all possibilities?
When asked to find all possibilities, rather than working on something they have been given (as is the case with sorting activities), children are required to generate something new . At first they are likely to do this in a random way. If you help them to sort their randomly-generated possibilities, then they can see which ones are missing.
