Question

A letter is selected at random from the set of English alphabets. What is the
probability that it is a vowel ?​

Answer 1

Answer:

n(S)=26

There are 5 vowels.......Event A

n(A)=5

p(A) =n(A)/n(S) =5/26

Answer 2

Answer:

n(s)=26

n(s)=26A={vowels}

n(s)=26A={vowels}n(A)= 5

n(s)=26A={vowels}n(A)= 5P(A)= n(A)/n(s)

n(s)=26A={vowels}n(A)= 5P(A)= n(A)/n(s) = 5/26
