A letter is randomly taken from English alphabets. What is the probability that the letter selected is not a vowel?
5/25
2/25
5/26
21/26
Explanation:
Total number of alphabets,$ n\left(S\right)$ = 26
Total number of characters which are not vowels, $n\left(E\right)$ = 21$\text{P(E) = }\dfrac{\text{n(E)}}{\text{n(S)}} = \dfrac{21}{26}$
