1/10
Someone can correct me if I'm wrong, but you have 10 dials, 1/10 chances.
A combination lock has 10 dials. To
open the lock, you must turn the dial right to the first number, left to
the second number. What is the probability that you choose the correct combination?

assuming the same number can be used on the 2nd turn
the number of turns = 10*10 = 100
One of these will be correct
prob of correct choice = 1/100
the number of turns = 10*10 = 100
One of these will be correct
prob of correct choice = 1/100
