The combination probability is then: If you draw three random balls from the bag, in 75% of cases, you'll pick a red ball. Means "any item, followed by c, followed by zero or more items, then f", And {b,c,f,g} is also allowed (there are no items between c and f, which is OK). @Brian M. Scott I would like to know the list of all possible combinations not just the number. You can use the following combination formula that will allow you to determine the number of combinations in no time: The exclamation mark !!! @JamesVickery yes, you could look at either making a list outside of the function and appending to that, or (better) make the function a generator, have a look at the 'yield' keyword :). Acoustic plug-in not working at home but works at Guitar Center. Let's check this combination property with our example. Sounds simple, right? Once all 3 tables have been loaded, go back into the Power Query editor by clicking Data > Get Data (dropdown) > Launch Power Query Editor. Select next combination A B C D E F G H I J K L M N Thanks for pointing that out! Unique combinations (order does not matter; items repeat): To subscribe to this RSS feed, copy and paste this URL into your RSS reader. anyone know how to modify this to reflect 6 columns of data, rather than just two? Well, it depends on whether you need to take order into account or not. There is just one warning from me. Once you have decided where the result will appear, paste in the formula as shown in figure 1 below; Figure 1: All possible combinations formula. If you're after an even more in-depth explanation, the permutation calculator should satisfy this need. The file is very large. i need to get a list of all possible combinations, not permutations. Your privacy is guaranteed. Futuristic/dystopian short story about a man living in a hive society trying to meet his dying mother. So you have options: 1: convert the item to a list first: this is very good and pointed me to what really solved my problem, which was, the function writes intertools.combinations_with_replacement. When you return the first ball, e.g., blue ball, you can draw it as a second and third ball too. Have you ever wondered what your chances are of winning the main prize in a lottery? There is the law of large numbers that describes the result of performing the same experiment a large number of times. How to calculate the combinations, then? This answer missed one aspect: the OP asked for ALL combinations not just combinations of length "r". A Real Example of Generating a List of all Possible Permutations in Excel Let's take a look at a sample spreadsheet that generates a list of all possible permutations given two lists. Click Kutools > Insert > List All Combinations, see screenshot: 2. In the List All Combinations dialog box, do the operations as below demo shown: 3. Your email address will not be published. After installing Kutools for Excel, please do as this: 1. It's an example in which you have four balls of various colors, and you choose three of them. Here's a lazy one-liner, also using itertools: Main idea behind this answer: there are 2^N combinations -- same as the number of binary strings of length N. For each binary string, you pick all elements corresponding to a "1". The table says to use the Binomial Coefficient ($nCr$) but we will have to use it 4 times & + up the results to account for your 4 differently sized subsets $$\style{font-family:inherit}{\text{# Combinations}} = 4C1 + 4C2 + 4C3 + 4C4 = \left(\begin{smallmatrix} 4 \\ 1 \end{smallmatrix}\right) + \left(\begin{smallmatrix} 4 \\ 2 \end{smallmatrix}\right) + \left(\begin{smallmatrix} 4 \\ 3 \end{smallmatrix}\right) + \left(\begin{smallmatrix} 4 \\ 4 \end{smallmatrix}\right) = 15$$, Here you can input your options and get all possible combinations: mathisfun.com.
