Why is there only one possible combination here?
I got stuck right at the end of my game, and got the following hint:
What am I missing? What logic dictates that only one combination is possible?
Best Answer
The third column already has 5 blues, and only 3 reds. Since you must have an equal number of tiles of each color in each column/row, both remaining squares in the third column (including the leftmost of the two highlighted) must be red. Then, the other highlighted square, being in the same row, must be blue so that row has an equal number of reds and blues.

How do you find how many possible combinations?
To calculate combinations, we will use the formula nCr = n! / r! * (n - r)!, where n represents the total number of items, and r represents the number of items being chosen at a time. To calculate a combination, you will need to calculate a factorial.What is the rule for combination?
Dempster's rule of combination is a rule for combining two or more belief functions; when the belief functions combined are based on distinct or \u201cindependent\u201d sources of evidence, the rule corresponds intuitively to the pooling of evidence.How do you find all possible repetition combinations?
If we are selecting an r-combination from n elements with repetition, there are C(n+r-1,r)=C(n+r-1,n-1) ways to do so. Proof: like with the candy, but not specific to r=6 and n=3....Combinations with Repetition.Order?Repetition?FormulaNo (combination)YesC(n+r-1,r)=\\frac{(n+r-1)!}{r!(n-1)!}3 more rowsWhat are the two types of combinations?
There are also two types of combinations (remember the order does not matter now):...Combinations- Combinations with Repetition. ...
- Combinations without Repetition. ...
- Combinations with Repetition.
