WebPermutation Example For permutations, the order matters. Suppose we need to know the number of possibilities for a four-digit lock. There are 10 possible values, and we’re picking 4. Statisticians state this scenario as “10 choose 4” and denote it as 10 P 4, where P indicates we’re working with permutations.

WebApr 12, 2024 · For example, with four-digit PINs, each digit can range from 0 to 9, giving us 10 possibilities for each digit. We have four digits. Consequently, the number of permutations with repetition for these PINs = 10 * 10 * 10 * 10 = 10,000. We write this mathematically as n r. Where: n = the number of possible outcomes for each event. WebJan 21, 2024 · Here is how we do that: We have 13 numbers so choosing 1 of 13 is given by 13 choose 1. Once the number is selected we need to choose two colors from four which is given by 4 choose 2. Choose 3 numbers from the remaining 12 numbers = 12 choose 3. For each number of the three choose a color from 4 colors = 4 choose 1.
