Question:
A letter is chosen at random from the word ‘ASSASSINATION’. Find the probability that letter is
(i) a vowel
(ii) an consonant
Solution:
There are 13 letters in the word ASSASSINATION.
$\therefore$ Hence, $n(S)=13$
(i) There are 6 vowels in the given word.
$\therefore$ Probability (vowel) $=\frac{6}{13}$
(ii) There are 7 consonants in the given word.
$\therefore$ Probability (consonant) $=\frac{7}{13}$
