Question

A letter of English alphabet is chosen at random. Determine the probability that the chosen letter is a consonant.

Answer 1

Let E be the event of getting a consonant.

Out of 26 letters of English alphabets, there are 21 consonants.

∴ P(getting a consonant) = P(E) = `"Number of outcomes favourable to E"/"Number of all possible outcome" = 21/26`

Thus, the probability of getting a consonant is `21/26`
