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?

a.21/5

b.1/40

c.42/5

d.21/100

Probability of choosing  a consonant and then a vowel=P(first consonant)*P(vowel with replacement)

  =[28/(28+12)]*[12/(28+12)]

  =21/100
