A letter is chosen at random from the word $\mathrm {'ASSASSINATION'}$. Find the probability that letter is a vowel.
There are $13$ letters in the word $\mathrm {'ASSASSINATION'}$.
$\therefore$ Hence, $n( S )=13$
There are $6$ vowels in the given word.
$\therefore $ Probability (vowel) $ =\frac{6}{13}$
