To find the probability of choosing any letter in the alphabet (at random) out of a book or other written source, would you use theoretical or experimental probability? WHY?

Question

First of all, you should know what's the difference between theoretical and experimental probability. Theoretical is based on calculations while experimental is based on actual conducting/gathering of information. So what do you think you should use when choosing a random letter in the alphabet out of a book? Are you going to calculate the probabilities or is it easier to try doing it?
