What is a circular combination?

^ Thanks for helping kanika! I was wondering whether there is a formula to derive the number of possible combinations (for a circular arrangement). If you do know the answer, please help!


How many symbols can you make with a 7 LED grid?

In a 7 segment display, the symbols can be created using a selected number of segments where each segment is treated as a different element.When 1 segment is used, the possible positions are 7because it can be any of the 7 segments (7C1=7).When 2 segments are used, the number of possible combinations are 7C2=21.When 3 segments are used, the number of possible combinations are 7C3=35When 4 segments are used, the number of possible combinations are 7C4=35When 5 segments are used, the number of possible combinations are 7C5=21When 6 segments are used, the number of possible combinations are 7C6=7When 7 segments are used, the number of possible combinations are 7C7=1Adding the combinations, 7+21+35+21+7+1=127Therefore, 127 symbols can be made using a 7 segment display!


What are the 5-number combinations not using any number twice?

There are infinitely many numbers and so infinitely many possible combinations.


What are the possible combinations of a 3 digit lock for numbers 0 through 39?

Assuming that repeated numbers are allowed, the number of possible combinations is given by 40 * 40 * 40 = 64000.If repeated numbers are not allowed, the number of possible combinations is given by 40 * 39 * 38 = 59280.


How many different combinations are possible is a coin is tossed once and a number cube is tossed twice?

The number of combinations - not to be confused with the number of permutations - is 2*21 = 42.

How many liquid combinations can you make?

There are countless possible liquid combinations, depending on the types of liquids you are considering (water, juice, alcohol, etc.) and how many you want to mix together. The number of combinations would be exponential, as each additional liquid increases the number of possible combinations exponentially.

A carrier wave is modulaated with 8amplitudes and 8 phase changes How many possible signal combinations are there?

To determine the number of possible signal combinations for a carrier wave modulated with 8 amplitudes and 8 phase changes, you multiply the number of amplitude options by the number of phase options. Thus, the total combinations would be (8 \times 8 = 64). Therefore, there are 64 possible signal combinations.
