• math -

1. key position and size
The white keys are different in size than the black keys, and they are not placed in the same location.
2. the mid octaves are more easily accessible than the very high and very low octaves.

Assuming complete random choice of the keys (which is not true), there are 88 choices out of which we choose one key.

What is the probability of hitting one particular key assuming complete random choice, and knowing that all probabilities have to add up to 1 (Kolmogorov's axiom 2)?
