How many letters are there in the alphabet? 26
How many vowels are there in the alphabet? 5
Therefore, the probability of picking one vowel is 5/26.
The probability of picking N vowels is (5/26)^N or 5/26 * 5/26 * 5/26.... (N times).
So for your question, the answer is (5/26)^5 = 0.03% when rounded to the nearest hundredth of a percent.
