Use the uniform probability model to find the probability of selecting a vowel letter from the word MODELS .
There are 6 letters in the word MODELS, and 3 of them are vowels (O, E, and S).
So, the probability of selecting a vowel letter from the word MODELS is:
Number of favorable outcomes (vowels): 3
Total number of possible outcomes: 6
Probability = Number of favorable outcomes / Total number of possible outcomes
Probability = 3 / 6
Probability = 0.5
Therefore, the probability of selecting a vowel letter from the word MODELS is 0.5 or 50%.
