Dear ma’am, how did you get 0.5 for p in the example using binomial distribution? Please answer!

This video is less helpful. All you are doing is just book questions and copy pasting solved questions from the book itself. If you don’t solve past papers then it’s useless. You need to solve past papers as well.
