[ENEM 2020 DIG] 140 📘 ANÁLISE COMBINATÓRIA Eduardo deseja criar um e-mail utilizando um anagrama

[140] Eduardo wants to create an email address using an anagram exclusively with the seven letters that make up his name, before the @ symbol. The email will have the form *******@site.com.br and will be such that the three letters "edu" always appear together and in exactly that order. He knows that the email address [email protected] has already been created by another user and that any other grouping of the letters of his name forms an email address that has not yet been registered. In how many ways can Eduardo create a desired email address? ✅ SUPER [WORKSHEET] PROF.
