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?

You have a typo:
There are 28 students taking Hindi, 26 taking Hindi and 16 taking English.

And this amazes me how people can come ask a question, and even having been replied to, will ignore it and ask the same replica of the question they initially asked...

Man, you hit that nail on the head, U. Rather perplexing, isn't it? Or, post a problem, it gets answered, then never hear from them again.
I believe they repost the same problem if it hasn't been answered to their satisfaction. They probably want a step-by-step solution. If it is not given, try posting again.
