Hi there,
There was a test math question and I thought I got the right answer:
A group of 8 eight people were waiting to get into a restaurant, what is the probability of me the first to get inside (only 1 person gets pick at a time.)
My answer was 8. But my teacher said it should be 1/5040 (8C1 divided by 2 factorial). How does it work?
