In a class of 34 students… > 12 study German
> 25 study Spanish
> 6 do not study either language

One student in the class is selected at random.

Find the probability that this student studies both languages.

My answer to this question would be :

6 = 34 - (12+25) + X

6 = -3 + X

9 = X

The probability would be : 9/34 = 0.26

I am not really sure i will check it later and tell you .

I would be happy if you let me know it was wrong or not , too .
