Given, ‘ASSASSINATION’

No. of A's = 3; No. of S's = 4; No. of I's = 2; No. of N's = 2; No. of T = 1; No. of O = 1

No. of letters = 13

No. of vowels = {3 A's,2 I's,O} = 6

One letter is selected:

n(S) = ^{13}\textrm{C}_{1} = 13

Let E be the event of getting a vowel.

n(E) = ^{6}\textrm{C}_{1} = 6

\therefore P(E) = \frac{6}{13}
