42/5

21/100

21/5

1/40

Listed above are all possible answers!

Answer 2

The is a total of 28 + 12 = 40 tiles. The probability of choosing a consonant first is 12/40. The probability of drawing a vowel next is 28/40. The events are independent, therefore the required probability is given by:
\[\frac{12}{40}\times\frac{28}{40}=you\ can\ calculate\]

Answer 3

Nope. It does calculate to one of the options. Try some simplifying by cancelling.
