Help needed with multi variable events
I hope this is the right place to ask this question.
I have large number of events
Each event has 8 variables which are independent.
Each event has 3 possible results, and in this instance I'm only interested in result A
Each variable occurs X% of the time, and when each variable occurs A occurs Z% of the time.
Given the 8 variables are a-h, what % of the time will all 8 variables occur at the same? And what will Z be when all variables occur?
I hope all that makes sense
Thanks in advance
