Question

A letter is chosen from the word 'PROBABILITY'. What is the probability that the letter chosen is a consonant?

• A. $\frac{5}{11}$
• B. $\frac{4}{11}$
• C. $\frac{7}{11}$
• D. $\frac{9}{11}$

Answer 1

The correct option is C

$\frac{7}{11}$

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

Number of consonants in the word = P, R, B, B, L, T, Y

= 7

$\therefore$ The probability of getting a consonant = $\frac{Numberoffavourableoutcomes}{Totalnumberofpossibleoutcomes}$

= $\frac{\text{Number of consonants}}{\text{Total number of letters}}$

= $\frac{7}{11}$
