How to know the number of possible combinations?

Combinations room a method to calculation the in its entirety outcome of an occasion where the order of the outcome no matter. To calculate the combinations we use the formula nCr = n! / r! * (n r) !, whereby n is the total number of elements and r is the variety of elements selected at one time so how plenty of number combinations room there?

Correct answer: for the letters there space 26 possibilities for each of the 3 tracks and also for the numbers there space 10 possibilities because that each of the 3 tracks. The total number of combinations is therefore: 26 x 26 x 26 x 10 x 10 x 10 = 17,576,000 ≈ 18 million.

How countless four-digit 12-digit combinations room there?

For each choice of the first two digits, you have 10 selections for the 3rd digit. For this reason you have 10x10x10 = 1000 choices for the first three digits. After all, you have ten choices for the 4th digit, for this reason there are 10x10x10x10 = 10,000 feasible 4-digit combine from 09.
