5 letters are typed, with repetition allowed. What is the probability that all 5 will be vowels? Write your answer as a percent. Round to the nearest hundredth of a percent as needed

Answer 1

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.
