on the home work I got the 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.
This is given by ... (probability of consonant on first draw) x (probability of vowel on the second draw) =
12/40 x 28/40 =
3/10 x 7/10 =
21/100
