Question
How many different words (with or without meaning) can be made using all the vowels at a time?
Correct Answer
Option C is the correct answer.
Detailed Explanation
The English vowels are A, E, I, O, U. There are 5 distinct vowels. To form words using all of them at a time, we need to find the number of permutations of 5 distinct objects. This is 5! (5 factorial) = 5 * 4 * 3 * 2 * 1 = 120.
Hint
Identify the number of distinct vowels and then calculate the factorial of that number.
