Ola pessoal,

Resolvi o problema abaixo e minha resposta foi 11. Sera que resolvi certo, pois nao tenho o gabarito ?
ps: resolvi por Venn-Euler

In a class of 39 students, besides speaking English, every
student speaks at least one of the following second languages:
Mandarian, Malay and Tamil. 26 students speak Mandarian, 16
speak Malay and 8 speak Tamil. No student speaks all three of
these second languages. How many pupils speak two of these
second languages?
