You are correct that there are 10^8 possibilities for a string of 8 digits. 10 possibilities in position 1 10 possibilities in position 2 ... 10 possibilities in position 8 10 * 10 * 10 * 10 * 10 * 10 * 10 * 10 Alternatively one can even simply observe that 99999999 is the highest number possible and since 00000000 is possible also then we have 99999999 + 1 different possibilities = 100000000 = 10^8 |
