MCQ

A single letter is selected at random from the word “$PROBABILITY$”. The probability that the selected letter is a vowel is

A
$\frac{2}{{11}}$
B
$\frac{3}{{11}}$
✓
$\frac{4}{{11}}$
D
$0$

✓

Answer

Correct option: C.

$\frac{4}{{11}}$

c
(c) Since there are one $A,$ two $I$ and one $O,$

hence the required probability $ = \frac{{1 + 2 + 1}}{{11}} = \frac{4}{{11}}.$
