Answer:
25 / 676
Step-by-step explanation:
There are 5 vowels in the alphabets, and there are 26 alphabets in total as a whole.
The probability of drawing a vowel kb first trial is going to be
5 / 26, total number of vowels and total number of alphabets as a whole.
Again, we're told to replace the picked vowel, and pick another vowel, so that will once again be
5 / 26.
To get the final answer, we multiply both answers by each other
5 / 26 * 5 / 26 = 25 / 676.
Therefore, the probability has been found to be 25 / 676
