The rule of probability

WebbP ( A ∩ B ) = P (A) x P (B) This rule only applies when the two events are independent. This is not always a given. What independence means is that the probability of event B is the same whether or not even A occurred. In this case, there is (overall) a 12/29 = 0.41 chance of drawing something Yellow. WebbRule 1: The probability of an impossible event is zero; the probability of a certain event is one. Therefore, for any event A, the range of possible probabilities is: 0 ≤ P (A) ≤ 1 Rule 2: For S the sample space of all possibilities, P (S) = 1. That is the sum of all the …

For example, if \(A\) is the probability of hypertension, where \(P(A)=0.34\), then the complement rule is: \[P(A^c)=1-P(A)\]. In our example, \(P(A^c)=1-0.34=0.66\).This may seen very simple and obvious, but the complement rule can often …
