Well, this is how probability works! $$. 3. You now need to select a cell where you want to have the result of possible combinations to appear. Example: has 2,a,b,c means that an entry must have at least two of the letters a, b and c. The "no" rule which means that some items from the list must not occur together. Briefly, permutation takes into account the order of the members and combination does not. If you want to save hours of, research and frustration, try our live Excelchat service!

It has rejected any with a and b, or a and c, or b and c, or even all three a,b and c. So {a,d,e) is allowed (only one out of a,b and c is in that), But {b,c,d} is rejected (it has 2 from the list a,b,c), {a,b,d} {a,b,e} {a,c,d} {a,c,e} {a,d,e} {b,c,d} {b,c,e} {b,d,e} {c,d,e}, Only {a,b,c} is missing because that is the only one that has 3 from the list a,b,c.

The wording of the problem does not make it clear whether you can choose the empty set of foods. This is an approach that can be easily transfered to all programming languages supporting recursion (no itertools, no yield, no list comprehension): This one-liner gives you all the combinations (between 0 and n items if the original list/set contains n distinct elements) and uses the native method itertools.combinations: You can generate all combinations of a list in Python using this simple code: I thought I would add this function for those seeking an answer without importing itertools or any other extra libraries.
