Hi, My instructor gave an example in class today about difference between probability and statistics. He used the following example: Suppose we flip a fair coin 10 times. What sis the probability of fetting 9 0r more heads? He said the answer was 11/1024. He never showed us how to compute this and said it was simply the addition of two value to get 11/1024. How do you compute this? Thank you for any advice.
