math: simple
posted by Brooke .
A locker combination has two nonzero digits, and digits can be used twice. The first number is 8. What is the probability that the second number is 8?

I am confused by your description. Does "two nonzero digits" mean that there are two digits beside zero? If so, how do you get an 8?
The answer would be 1 divided by the total number of possibilities.
I hope this helps. Thanks for asking.
