$\huge{\underline{\mathtt{\red{q}\pink{u}\green{e}\blue{s}\purple{t}\orange{i}\blue{o}\purple{n}}}}$

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

$\huge{\underline{\mathtt{\red{A}\pink{N}\green{S}\blue{W}\purple{E}\orange{R}}}}$

Total English alphabets = 26

Number of consonants = 21

∴ P (letter is a consonant) = 21/26

Answer 2

Answer:

There are 26 letters in English alphabets.

∴ Total number of outcomes = 26

We know that there are 5 vowels and 21 consonants in English alphabets.

∴ Total number of favourable outcomes = 21

∴ Probability that the chosen letter is a consonant = total number of favourable outcomes/total number of outcome.

=21/26
