\displaystyle\huge\red{\underline{\underline{Solution}}}

The number of ALPHABETS in the word "PROBABILITY" is 11

So the total number of possible outcomes = 11

Let A be the EVENT that the selected letter is VOWEL

So the total number of possible outcomes for the event A is 4

So the REQUIRED probability = P(A) = \displaystyle \:  \frac{1}{4}
