The letter tiles W, I, S, D, O, M are placed on a box. Without looking, Abby picks a letter tile from the box. What is the probability that the letter she picks is a vowel? Write your answer in the simplest form of a fraction.(1 point)

There are 6 letter tiles in the box, with only 2 vowels (I and O).

Therefore, the probability of Abby picking a vowel is 2/6.

Simplifying the fraction, we get 1/3.

So, the probability that the letter Abby picks is a vowel is 1/3.
