100-students

28-spanish

12-both spanish and french⇒ 28-12-2-4=10 only spanish

2-in all classes

4 - spanish and tagalog

16 - tagalog

4 - spanish and tagalog

2 - all classes

6 - french and tagalog ⇒ 16-6-2-4=4 only tagalog

26-french

12-french and spanish

2-all classes

6-french and tagalog ⇒ 26-12-2-6 = 6 only french

the students who are in language classes are:

10+6+4+2+12+6+4=44

100-44=56 are not in language classes

P=56/100=0,56
