finoq SG Forgot my Combinations and Permutations liaoz... a combination lock with 3 digits has how many possible combinations (including starting with 0) and how to calculate?
FireIce SG first digit possibilities = 0 to 9 = 10 second digit possibilities = 0 to 9 = 10 third digit possibilities = 0 to 9 = 10 10^3 = 1000 other way to do all numbers, 000 to 999 inclusive 999 - 000 + 1 = 1000
