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 total. Of those 6 tiles, only 2 tiles (I and O) are vowels.

So the probability of Abby picking a vowel is 2 out of 6, which simplifies to 1 out of 3.

Therefore, the probability that the letter she picks is a vowel is 1/3.
