Question

A single letter is selected at random from the word 'PROBABILITY'. The probability that is a vowel, is

• A. $\frac{8}{11}$
• B. $\frac{4}{11}$
• C. $\frac{2}{11}$
• D. $\frac{3}{11}$

Answer 1

The correct option is B

$\frac{4}{11}$

Explanation for the correct option:

Total number of alphabets in “PROBABILITY” $=11$

Vowels in “PROBABILITY” are O, A, I, I

Number of vowels in “PROBABILITY” $=4$

Now, we can select 4 vowels at random.

Therefore, the favorable outcomes $=4$

Thus, the probability of getting a vowel at random $=\frac{4}{11}$

Hence, Option ‘B’ is Correct.
