Answer 1

A letter is chosen at random from all the letters of the English alphabets. The probability that the letter chosen is a vowel, is `underlinebb(5/26)`.

Explanation:

Total number of letters in English alphabets

n(S) = 26

Let E = Letter chosen is a vowel = {a, e, i, o, u}

∴ n(E) = 5

∴ Required Probability

P(E) = `(n(E))/(n(S)) = 5/26`
