Question

In a word game, you choose a tile from a bag, replace it, and then choose another. If there are 28 vowels and 12 consonants, what is the probability you will choose a consonant and then a vowel?

Answer 1

`21/100`

Explanation:

The numbers of vowels and consonants stay the same for the second tile, because the first tile was replaced.

The total number of tiles = 40.

`P(C, V) = P(C) xx P(V) " ", larr" both must happen"`

= `28/40 xx12/40 = 21/100`
