Web5 jan. 2024 · Solution: In this example, the probability of each event occurring is independent of the other. Thus, the probability that they both occur is calculated as: P (A∩B) = (1/30) * (1/32) = 1/960 = .00104. Example 2: You roll a dice and flip a coin at the same time. WebIf the matrix AB is zero, then A It is not necessary that either A=O or, B=O B A=O or B=O C A=O and B=O D All the above statements are wrong Medium Solution Verified by Toppr Correct option is A) Let us take A=[0400] and B=[0100]. Now, AB =[0400][0100] =[0000]. But none of A and B are zero matrices.

WebThe idea is that if a not equal to 0 then b = 0 also applies to the case when b is not equal to 0 then a = 0. The proof sometimes will clarify this but it might be left unstated. The idea is that ab = 0 is symmetrical for a and b, ie ab = ba so picking one essentially "proves" it for the other. 3 Reply [deleted] • 3 yr. ago
