A letter is chosen at random from the word ‘ASSASSINATION’. Find the probability that letter is (i) a vowel (ii) a consonant
Solution:
There are 13 letters in the word ‘ASSASSINATION’.
Hence, the number of elements in the sample space is, n (S) = 13
(i) There are 6 vowels in the given
V = {A, A, I , A, I , O}; n (V) = 6
The required probability is,
P (V) = n (V)/n (S)
= 6/13
(ii) There are 7 consonants in the given
C = {S, S, S, S, N ,T , N}; n (C) = 7
The required probability is,
P (C) = n (C)/n (S)
= 7/13
