How many four-character license plates consist of a consonant, followed by a vowel, followed by a consonant, and then a digit? (For this problem, consider Y a vowel.)
+247 There are 6 vowels, 20 consonatns and 10 digits.
For the first character there are 20 options, the second character 6 options, the third 20 options and the last 10 options.
Using the multiplication principle of counting gets 20*6*20*1 = \(\boxed{2400}\) possible license plates.
