Can someone link me to an accurate article, website, etc. that can properly show me how to calculate the probability or percentage of an event occurring based on various different percentages. Or even one where the percentages can be weighted differently.
Simple example not relating to what I'm trying to do but shows 4 different variables that would need to be computed.
What's the probability that Team A or B scores a run in the 1st inning if Team A normally scores a run 25 % of the time and allows its opposition to score 30% of the time and Team B scores 27% of the time and allows opponents to score 23% of the time.
Thanks in advance
