Each of the letters of the word MISSISSIPPI are written on a piece of paper and then put into a bag. A piece of paper is drawn at random. What is the theoretical probability of NOT drawing an I?

The word MISSISSIPPI has a total of 11 letters, including 4 I's. Therefore, there are 11 - 4 = 7 letters that are not I. The probability of not drawing an I is the same as the probability of drawing one of the 7 non-I letters, which is 7/11 or approximately 0.636.
