A letter is to be picked at random from the English alphabet. If each letter is equally likely to be selected, what is the probability of selecting a consonant? Consonants are letters except for a, e, i, o, and u. Write your answer in the simplest form of a fraction

There are 21 consonants in the English alphabet (all letters except for a, e, i, o, and u) out of a total of 26 letters.

Therefore, the probability of selecting a consonant is 21/26, which is the simplest form of the fraction.
