Question
A letter is chosen at random from all the letters of the English alphabets. The probability that the letter chosen is a vowel, is ______.
Options
`4/26`
`5/26`
`21/26`
`5/24`
Solution
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`
