The locker key is a combination of 3 different digits from 9 numbers (1 to 9).

This contains 5 odd numbers and 4 even numbers.

If the first digit is odd, there are 4 even digits in the remaining 8 numbers.

The probability that the second digit is even is \frac{4}{8} =\frac{1}{2}

Please give a simple summary of log functions.
Bess [88]
Logarithmic functions are the inverses of exponential functions. The inverse of the exponential funtion y = ax is x = ay. The logarithmic function y = logax is defined to be equivalent to the exponential equation x = ay. A logarithm is really nothing more than an exponent.
