Hii Guys...
Actually I've a question in mind.Its not a question from any text book.It just came to my mind and I felt like solving.
Suppose there are 60 questions.And there are 4 options to every question.
What is the probability that all the answers that I do are wrong??
I've solved it myself.But don't know if its right or wrong...
So it would be really nice if someone amongst you helps.....
To those who are attempting AIMCATs....
All those who think you need the print option for solutions of AIMCATs, please leave a message to the HEAD OFFICE. If a lot many request for the change, they might bring it back... 😃
