$\frac{4}{11}$

To calculate probability, we need to divide the number of chances for a certain outcome to occur by the total number of outcomes. In this case, there are four tiles with the letter "I" and $11$ tiles in total. When we divide $4$ by $11$, we get $\frac{4}{11}$, which is the probability of drawing "I."
