Answer
$\frac{7}{11}$
Work Step by Step
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 $4$ tiles with the letter "I" and $11$ tiles in total. This means that the other $11-4=7$ tiles must be "not I." When we divide $7$ by $11$, we get $\frac{7}{11}$, which is the probability of drawing a letter that is not "I," or $P(\text{Not I})$
