Question

What is the probability of choosing a vowel from the alphabets?

• A. $\frac{21}{26}$
• B. $\frac{5}{26}$
• C. $\frac{1}{21}$
• D. None of these

Answer 1

Answer: (B)

$\frac{5}{26}$

The English Alphabet has $26$ letters ($a$ to $z$) out of which $5$ are vowels ($a,e,i,o,u$).
Thus the probability of choosing a vowel from the alphabet = $\frac{{}^5{C}_1}{{}^{26}{C}_1}=\frac{5}{26}$
