Question -

A letter is chosen at random from the word ‘ASSASSINATION’. Find the probability that letter is (i) a vowel (ii) a consonant



Answer -

The word given in the question is ‘ASSASSINATION’.

Total letters in the given word = 13

Number of vowels in the given word = 6

Number of consonants in the given word = 7

Then, the sample space n(S) = 13

(i) a vowel

Let us assume ‘A’ be the event of selecting a vowel

n(A) = 6

P(A) = n(A)/n(S)

= 6/13

(ii) Let us assume ‘B’ be the event of selecting theconsonant

n(B)= 7

P(B) = n(B)/n(S)

= 7/13
