Web18 jul. 2024 · Two events are independent events if the occurrence of one event has no effect on the probability of the occurrence of the other event. Multiplication Rule for “And” Probabilities: Independent Events If events A and B are independent events, then P(A and B) = P(A) ⋅ P(B). Example 3.2.6: Independent Events for Tossing Coins WebI do not have any idea how to calculate this, but I do have the data points available. I have a computer system that has a setting for something -- garbage collection ("gc") -- to occur with p probability on any given time that a certain process runs (I'll call that process "the process"). I have the frequency of the process itself running.
