To find the probability of selecting a vowel letter from the word "MODELS," we first need to identify the vowel letters in the word. The vowels in the English alphabet are A, E, I, O, U. In the word "MODELS," the only vowel is E.
The word "MODELS" consists of 6 letters:
- M
- O
- D
- E
- L
- S
Out of these, there is 1 vowel (E).
The probability of selecting a vowel can be calculated using the formula:
\[ \text{Probability} = \frac{\text{Number of favorable outcomes (vowels)}}{\text{Total number of outcomes (letters)}} \]
So,
\[ \text{Probability} = \frac{1}{6} \]
Therefore, the correct response is:
Start Fraction 1 over 6 End Fraction.
