Webb27 mars 2024 · A useful property to know is the Additive Rule of Probability, which is P ( A ∪ B) = P ( A) + P ( B) − P ( A ∩ B) The next example, in which we compute the probability … WebbThis is the probability of having neither hypertension nor high cholesterol. P (Ac orBc) =1 −P (AandB) = 1−0.25 = 0.76 P ( A c o r B c) = 1 − P ( A a n d B) = 1 − 0.25 = 0.76. This is the probability of not having both conditions. The last two formulas are referred to as De Morgan’s Laws.
Webbminus the probability of A and B" Here is the same formula, but using ∪ and ∩: P(A ∪ B) = P(A) + P(B) − P(A ∩ B) A Final Example. 16 people study French, 21 study Spanish and there are 30 altogether.
