Reference no: EM13117702

Use the Fundamental Counting Principle to determine the number of 3-letter expressions possible under the following circumstances: The first letter must be a vowel (a, e, i, o, or u); the second letter can be any letter except a vowel; the third letter can be any letter of the alphabet. Remember that there are 26 letters in the alphabet.
