उत्तर
There are 26 letters of English alphabet.
Total number of outcomes = 26
Out of 26 letters, 21 are consonants and 5 are vowels.
Favourable number of outcomes = 21
∴ P(chosen letter is a consonant) = \[\frac{\text{ Favourable number of outcomes }}{\text{ Total number of outcomes }} = \frac{21}{26}\]
