For example, we can only read intersections from a contingency table. So, as soon as we're looking for the probability of a union, we need this handy formula – the addition rule. My approach is as follows: STEP 1: List the relevant events. Label the events/sets with a capital letter. STEP 2: Determine the cardinality of the relevant events. How many elements are in the set? ... STEP 3: Determine the relevant probabilities We need the probabilities of the two events as well as the probability of the intersection event. STEP 4: Apply the addition rule P(A ∪ B) = P(A) + P(B) - P(A ∪ B) Substitute the values ​​- calculate - easy :) --------MORE VIDEOS FOR YOU------------------- (1) Calculation session: Probability A-Levels 2018:    • RECHENSESSION: STOCHASTIK ABI 2018 (ohne H...   (2) Calculation session: Probability A-Levels 2019:    • RECHENSESSION: STOCHASTIK ABI 2019 (ohne H...   (3) A-Level Summary Probability: https://tinyurl.com/2wed8bvr (4) PLAYLIST: FOUR-FIELD TABLE: https://tinyurl.com/4tfm22ra
