The probability would be the product of the probability for each draw.

So, for the first draw, there are 11 tiles and 2 are the letter I. What is this probability.

For the second draw, assume he drew an I on the first one...now there are 10 tiles and 1 is the letter I. What is this probability?

Take those two probabilities and multiply them together.
