$\frac{5}{26}$
Probability of Choosing a Vowel
This question asks for the probability of randomly selecting a vowel from the English alphabet.
Identify Total Possible Outcomes
The English alphabet contains 26 letters. Each letter represents a total possible outcome.
- Total letters = 26
Identify Favorable Outcomes
The vowels in the English alphabet are A, E, I, O, and U. These are the specific outcomes we are looking for.
- Number of vowels = 5
Calculate Probability
Probability is calculated as the ratio of the number of favorable outcomes to the total number of possible outcomes.
The formula is:
$ P(\text{Event}) = \frac{\text{Number of Favorable Outcomes}}{\text{Total Number of Possible Outcomes}} $
For this specific question:
$ P(\text{Vowel}) = \frac{\text{Number of Vowels}}{\text{Total Number of Letters}} $
Substitute the identified values:
$ P(\text{Vowel}) = \frac{5}{26} $
Conclusion
The probability of randomly choosing a vowel from the English alphabet is $\frac{5}{26}$.
