Answer 1

In the word "MODELS", the letters are M, O, D, E, L, S.

The vowels in this word are O and E.

To find the probability of selecting a vowel, we identify the total number of letters and the number of vowels:

- Total letters = 6 (M, O, D, E, L, S)
- Number of vowels = 2 (O, E)

The probability \( P \) of selecting a vowel is given by:

\[
P(\text{vowel}) = \frac{\text{Number of vowels}}{\text{Total number of letters}} = \frac{2}{6} = \frac{1}{3}
\]

Thus, the probability of selecting a vowel letter from the word "MODELS" is **1/3**.
