Question

What is the probability of you selecting a vowel (A, E, I, O, U) and then, without returning it, selecting a consonant? Explain the steps to calculating this probability.

Answer 1

21/130

Explanation:

26 letters in alphabet

- 5 vowels

- 21 consonants

P(vowel) = 5/26

With no replacement, there are now 25 letters of which 21 are consonants

P(consonant) = 21/25

Multiply the two probabilities fo get 21/130
