BiNomial Distribution Formula
My question is in regards to the binomial distribution formula:
Here is the formula...
it seems to work perfectly when finiding the probability of Exactly 10 customers.
The problem I am having is I can use online Binomial calculators and get the answer.. but i was wondering what formula to use if you are trying to find the probability of for example X > 1 , X < 3
stuff where its not exactly X = 10 or X = 1....
Any help would be greatly appreciated.
THANKS in advance.
