Question

What is the probability of choosing a vowel from all the letters of the alphabet?

• A. $\frac{3}{26}$
• B. $\frac{1}{26}$
• C. $\frac{5}{26}$
• D. $\frac{2}{13}$

Answer 1

The correct option is C $\frac{5}{26}$

There are 26 letters in the alphabet of which 5 are vowels i.e, A, E, I, O, U.
Therefore, probability of choosing a vowel is
$\frac{Totalnumberoffavourableoutcomes}{Totalnumberofoutcomes}=\frac{5}{26}$
