Question

A letter of english alphabet is chosen at random . Find the probability that the letter so chosen is a consonant

Answer 1

No. of alphabets in English language=26
No. of vowels=5 that are a, i, e, o, u.
No. of consonants in English language=26-5=21
Probability= No. of Favourable outcomes/Total no. of outcomes.
Probability of getting a consonant if a letter is chosen at random = 21/26.

Answer 2

P(E) = No. of outcome/ Total No. of outcome

( No. of Consonant alphabets are 21)

( Total No. of alphabets are 26)

21/26
