The vowels in the word MODELS are O and E.

Probability of selecting O = 16/100 = 1/6
Probability of selecting E = 16/100 = 1/6

Therefore, the total probability of selecting a vowel letter from the word MODELS is:

1/6 + 1/6 = 2/6 = 1/3

So, the answer is 1/3 or Start Fraction 1 over 3 End Fraction.
