Question

Probability of not choosing a vowel from all the alphabets is.

• A. $\frac{20}{26}$
• B. $\frac{5}{26}$
• C. $\frac{21}{26}$
• D. $\frac{4}{26}$

Answer 1

The correct option is C $\frac{21}{26}$

The alphabet contains 26 letters.

Out of it 5 are vowels, A, E, I, O, U.

$\text{Probability of choosing a vowel}=\frac{\text{Number of vowels}}{\text{Total number of letters}}$

$=\frac{5}{26}$

Probability not choosing a vowel from the alphabets = 1 - Probability of choosing a vowel

$=1-\frac{5}{26}$

$=\frac{21}{26}$
