I need help with the following for some hobby-programme I’m writing at
home.
There are A bags that contain either a single RED or single BLACK ball.
B of the bags have a single RED ball in them B <= A
I have C of the bags in my possession C <= A
What is the probability that I DON’T have a bag that has a RED ball in it?
I suspect the way to work it out is... (1.0 – The probability I do
have a bag with a RED ball in it).
***
I need the most simplified formula for this.
