Question

What is the probability of getting a vowel in the English alphabet?

(a) \(\frac {1}{21}\)

(b) \(\frac {5}{19}\)

(c) \(\frac {5}{26}\)

(d) \(\frac {21}{26}\)

This question was posed to me in exam.

My question is from Theoretical Approach to Probability topic in portion Probability of Mathematics – Class 10

Answer 1

The correct choice is (c) \(\frac {5}{26}\)

Explanation: Total number of outcomes = 26

Favorable outcomes of getting a vowel = {a, e, i, o, u} = 5

P(E) = \(\frac {Number \, of \, favorable \, outcomes}{Total \, number \, of \, outcomes} = \frac {5}{26}\)
