Answer: I'm not so sure but my answer is 101 tiles.

Explanation:

Because the probability of choosing a vowel is 40%, and there are 72 consonants, so we would set up the equaiton like this:

72 times 40% (0.40) = 28.8 (round up to 29)

So we have 72 consonants and 29 vowels. Add them up:

72+29 = 101
