Let (A1,A2,A3) be event space for sample space S. Let B be event in the sample space S. Explain whether the following statement is correct P(B)= P(B ∩ A1) +P(B ∩ A3)
so A1,A2 and A3 are event spaces B is event too the same so from these ALL i think that this is in different how you wann intersecting B by A1 or B by A3 or by indifferent spaces from these ALL so from this result that an event space intersected by an second event space the resulted space will be event sure
sorry but is true that my answer not is explanation on this statement but i think that from this property of sapec S not can be proven that this statemnet is correct or not
property of space S sorry for this mystec
