I know there are people on here whose math is way better than mine
and I'm about to prove it. My 10+ year old high-school maths has abandoned me (in fact, I think we did this stuff when I was 16. Yipe!) and I think all my textbooks are long gone, too.
I'm preparing a spreadsheet of probabilities. I have a situation where I am performing multiple tests of known probability. I need to know the probability that one of them will return true.
For example, I flip a coin four times. What is the chance that at least one will come up heads? (I could map out the sample space and come up with an answer that way; I specifically need a mathematical statement that will return the probability)
Anyone able to help me out here? Even with a link or some such? :/
