How many three digits can I get out of 6 numbers?
Interesting, can you explain how you arrived at that answer?
To calculate the number of possible three digit numbers, we use the formula nP3, where n is the total number of available digits and 3 is the length of the number we want to form. In this case, n=6 and 3=3, so it becomes 6P3 which is equal to 120. But since we cannot form numbers with repetition, we have to subtract the number of 3 digit numbers formed by repeating digits. That gives us a total of 20 unique three digit numbers.
