Solution

The correct option is D $\frac{5}{13}$
Total number of outcomes (letters in the word) = 13
Favourable outcomes (vowels in the word) = EEAIE
Number of favourable outcomes = 5

$Probability P(E) = \frac{Number of outcomes favorable to E}{Number of all possible outcomes of the experiment} = \frac{5}{13}$
