Question

A letter is chosen at random from the letters of the word "SILVERZONE". The probability that the letter chosen is not a vowel is :

• A. $\frac{3}{5}$
• B. $\frac{2}{5}$
• C. $\frac{1}{5}$
• D. $\frac{1}{9}$
• E. None of these

Answer 1

The correct option is A $\frac{3}{5}$

Number of non vowels in the word SILVERZONE = 6 (S, L, V, R, Z, N)
Total number of letters in the word = 10
Thus, the probability of choosing a non vowel $=\frac{6}{10}=\frac{3}{5}$.
