What about it don't you understand?
It's binomial probability, testing to see the maximum number of appointments that can be booked while still having a 90% chance of all the patients who turn up still being able to be seen

whne doing the binomial probability what power would you put 0.2 to?
how many powers can test for 0.2 before moving to n=18, n=19

0.2 goes to the power of x
You're testing to see if you can book 18 appointments while only having 16 turn up, so you test up to x=2 for 18, and up to x=3 for 19.
