In order to find this out, we just needed to find out which one has the same smallest fraction
25 / 35. Divided this by 5 and we will get 5/7 >>> smallest fraction
15/21 . Divided this by 3 and we also will get 5/7 >> smallest fraction
So the answer would be : B. 15/21
hope this helps

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
![\dfrac{50}{100} =0.5](https://tex.z-dn.net/?f=%5Cdfrac%7B50%7D%7B100%7D%20%3D0.5)
B. If a student is chosen randomly, the probability that he or she is taking exactly one language class is
![\dfrac{8+10+14}{100}=0.32](https://tex.z-dn.net/?f=%5Cdfrac%7B8%2B10%2B14%7D%7B100%7D%3D0.32)
C. If 2 students are chosen randomly, the probability that both are not taking any language classes is
![0.5\cdot 0.5=0.25](https://tex.z-dn.net/?f=0.5%5Ccdot%200.5%3D0.25)
So, the probability that at least 1 is taking a language class is
![1-0.25=0.75](https://tex.z-dn.net/?f=1-0.25%3D0.75)
