Question

A letter is chosen from the word 'MATHEMATICS'. What is the probability that the chosen letter is a vowel?

• A. $\frac{4}{10}$
• B. $\frac{4}{11}$
• C. $\frac{3}{11}$
• D. $\frac{3}{10}$

Answer 1

The correct option is B

$\frac{4}{11}$

Total number of letters in the word 'MATHEMATICS' = 11

Number of vowels in the word = A, E, A, I

= 4

$\therefore$ The probability of gettting a vowel = $\frac{\text{Number of favourable outcomes}}{\text{Total number of possible outcomes}}$

= $\frac{4}{11}$
