statistic
In a management class of 100 students' three languages are offered as an additional subject viz. Hindi, English and Kannada. There are 28 students taking Hindi, 26 taking Hindi and 16 taking English. There are 12 students taking both Hindi and English, 4 taking Hindi and English and 6 that are taking English and Kannada. In addition, we know that 2 students are taking all the three languages.
I) If a student is chosen randomly, what is the probability that he/she is not taking any of these three languages?
ii) If a student is chosen randomly, what is the probability that he/ she is taking exactly one language?

This question should have been under math homework, not business, careers, or accounting.
Second, we aren't here to answer the entire question for you, but to help with specific stumbling blocks after you try.
Third, you copied sentences 2 and 3 wrong, showing Hindi + English groupings twice for different numbers of people.
Lastly, it isn't clear if the students taking more than 1 language are a subset of those taking them singly. Especially since they don't add up to 100 either way you look at it.
