WebApr 23, 2024 · If both of the events have positive probability, then independence is equivalent to the statement that the conditional probability of one event given the other is the same as the unconditional probability of the event: \[\P(A \mid B) = \P(A) \iff \P(B \mid A) = \P(B) \iff \P(A \cap B) = \P(A) \P(B)\] This is how you should think of independence: … WebAssuming an even distribution of men and women, yes. So for example you have 100 people of which 50 are men and 50 are women, an 10% are left handed, then you 10 left handed people. 12% of those men are left handed. So that's 6 men and 10 - 6 is 4, so … So, the probability that the student doesn't know the answer AND answers correctly …

WebIn statistics, an exchangeable sequence of random variables (also sometimes interchangeable) is a sequence X 1, X 2, X 3, ... (which may be finitely or infinitely long) whose joint probability distribution does not change when the positions in the sequence in which finitely many of them appear are altered. Thus, for example the sequences ,,,,, … WebA are conditionally independent of X B given X C. The set of distributions that is globally Markov with respect to Gis denoted by P(G).
