What is the probability of selecting a constant from the alphabet?

The probability of selecting a constant from an alphabet depends on the specific alphabet in question and the number of constants it contains. For example, in the English alphabet consisting of 26 letters, if we consider constants to be consonants (21 in total), the probability of selecting a consonant randomly would be 21/26. Thus, the probability can be calculated by dividing the number of constants by the total number of characters in the alphabet.
