A combination lock has 4 dials, each with the digits 2, 3, 4, and 5. 
What is the probability that someone could guess the correct combination on the first try by randomly selecting a number from 2 to 5 four times?

10,000 combinations because you can go up to 9999

According to the question, the dials don't go up to nine.

4 dials with digits  1 2 3 4

   4 x 4 x 4 x 4 = 4possible combinations    = 256 possibles     

       you have a 1 in 256 chance of guessing it on one try
