WebFirst of all, P ( A or B) = P ( A) + P ( B) − P ( A and B) is always true. Since P ( A) = 0.15 and P ( B) = 0.10, the maximum value of P ( A or B) is obtained if P ( A and B) is at its minimum possible value which is 0. P ( A and B) = 0 means there is no overlap between A and B (the left knee and the right knee will never be sore at the same time). WebFor every probabilistic experiment with a sample space Ω, we can define a trivial σ -algebra that contains { ϕ, Ω }. ϕ is defined to be the impossible event and P ( X = ϕ) = 0. …
