Answer:
A. 0.5
B. 0.32
C. 0.75
Step-by-step explanation:
There are 
- 28 students in the Spanish class, 
- 26 in the French class, 
- 16 in the German class, 
- 12 students that are in both Spanish and French, 
- 4 that are in both Spanish and German, 
- 6 that are in both French and German, 
- 2 students taking all 3 classes.
So, 
- 2 students taking all 3 classes, 
- 6 - 2 = 4 students are in French and German, bu are not in Spanish, 
- 4 - 2 = 2 students are in Spanish and German, but are not in French, 
- 12 - 2 = 10 students are in Spanish and French but are not in German, 
- 16 - 2 - 4 - 2 = 8 students are only in German, 
- 26 - 2 - 4 - 10 = 10 students are only in French, 
- 28 - 2 - 2 - 10 = 14 students are only in Spanish.
In total, there are 
2 + 4 + 2 + 10 + 8 + 10 +14 = 50 students. 
The classes are open to any of the 100 students in the school, so
100 - 50 = 50 students are not in any of the languages classes.
A. If a student is chosen randomly, the probability that he or she is not in any of the language classes is

B. If a student is chosen randomly,  the probability that he or she is taking exactly one language class is

C. If 2 students are chosen randomly,  the probability that both are not taking any language classes is

So,  the probability that at least 1 is taking a language class is

 
 
        
             
        
        
        
The intersection of two sets A and B is defined as the set composed by the elements appearing in both A and B.
So, the intersection is

Because all the other numbers do not belong to both sets:
- 2, 3 and 7 belong to A alone
- 13, 15 and 17 belong to B alone
- 5 and 11 belong to both A and B
 
        
             
        
        
        
Answer:7h-2
Step-by-step explanation:
take away 2 indicates -2
7 times h indicates 7h
then you have a few ways to write this out either: -2+7h or 7h-2 
both are correct!
