WebB given A" and is written:P(B A) General Multiplication Rule Always works. P(A and B) = P(A) * P(B A) Example 4: P(A) = 0.20, P(B) = 0.70, P(B A) = 0.40 A good way to think of P(B A) is that 40% of A is B. 40% of the 20% which was in event A is 8%, thus the intersection is 0.08.

WebDec 21, 2024 · Since P ( A ∩ B) is probability of the intersection of event A and B and P ( A ∩ B ¯) is the intersection of event A and not B and P ( B ∩ B ¯) = 0 as the set of B ∩ B ¯ is … WebProbability formula with multiplication rule: Whenever an event is the intersection of two other events, that is, events A and B need to occur simultaneously. Then P (A and B) = P (A)⋅P (B). P (A∩B) = P (A)⋅P (B∣A) Example 1: Find the probability of getting a number less than 5 when a dice is rolled by using the probability formula. Solution
