Even (related) chances (Posted on 2017-08-09) Difficulty: 3 of 5
Consider a string of n quaternary digits, randomly created.

Evaluate the probability that in this string the quantity
of an a priori defined digit, say zero, is even.

Double check your result by
a. direct count and comparison (e.g. n=4)
b. getting the same result by two distinct methods.
