3. For the following problem, the letters of the word "Mississippi" are written with one letter on each card. The cards are shuffled and placed face down. If one card is randomly selected, find the probability of the following: The letter is a vowel. $\frac{1}{4}$ $\frac{1}{3}$ $\frac{7}{11}$ $\frac{4}{11}$

Step 1 ：The word 'Mississippi' contains 11 letters.

Step 2 ：The vowels in 'Mississippi' are 'i' and 'i', which appear 4 times in total.

Step 3 ：So, the probability of drawing a vowel is the number of vowels divided by the total number of letters.

Step 4 ：\(\frac{4}{11}\) is the simplified form of the probability.

Step 5 ：Final Answer: The probability of drawing a vowel from the word 'Mississippi' is \(\boxed{\frac{4}{11}}\).
