Final answer:
The probability of randomly selecting a vowel from the given phrase is 3/7.
Step-by-step explanation:
To find the probability of selecting a vowel from the phrase, we need to determine the number of vowels and the total number of letters in the phrase. In the given phrase, there are 9 vowels (a, e, a, o, e, a, i, O, e) and 21 letters in total.
So, the probability of selecting a vowel is 9/21, which can be simplified to 3/7. Therefore, the correct answer is Option 1: 3/7.
