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, u. Write your answer in the simplest form of fraction.

There are 21 consonants in the English alphabet (excluding a, e, i, o, u) and there are a total of 26 letters in the alphabet.

Therefore, the probability of selecting a consonant is 21/26, which simplifies to 3/4.

So, the probability of selecting a consonant is 3/4.
