Probability of a and b not independent

Webb10 juli 2024 · Not independent would be the gender of each baby in a set of twins. If the twins are identical, then both of them will be male, or both of them would be female. Since A and B are independent so: = P (A) x P (B) so P [A B] = / P (B) = (P (A) x P (B)) / P (B) = P (A) In other hand A is not independent with B: = P (A) x P (B A) Webb5 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 …
