4 x 4 x 4 = 64 :)
There is 1 combination of all ten numbers, 10 combinations of one number and of nine numbers, 45 combinations of two or eight numbers, 120 combinations of three or seven numbers, 210 combinations of four or six numbers and 252 combinations of five numbers. That is 1023 = 210 - 1 in total.
If you have 12 possible numbers with multiple combinations then you should start out with making all the possible combinations; you will find theyre 20. Theyre four numbers out of the twleve that can be divisible by three; 3, 6, 9, and 12. There are 7 combinations where the combinations can equal those four numbers. So the odds of getting a sum divisible by three is 7/20.
4!=4x3x2x1=24
How many numbers are there are in each combination ?If one, then 4 combinations.If two, then 6 combinations.If three, then 4 combinations.If four, then only 1 combination.

shut up guys
To calculate the number of different seven-character license plates where the first four characters are letters and the last three are numbers, we consider the following: There are 26 letters in the English alphabet, so for the first four positions, there are (26^4) combinations. For the last three positions, which are numbers (0-9), there are (10^3) combinations. Therefore, the total number of different license plates is (26^4 \times 10^3).
Four outcomes, three combinations.
