then a and b complement are independent
Are A and its complement independent?
Events A and its complement are independent.
Is the complement independent?
If A and B are independent events then A complement and B complement are also independent events.12 août 2021
Two events are independent if the occurrence of one event does not affect the chances of the occurrence of the other event.
The mathematical formulation of the independence of events A and B is the probability of the occurrence of both A and B being equal to the product of the probabilities of A and B (i.e., P(A and B)

Complement: P(A)=1 ? P(A). If A and B are mutually exclusive then P(A ? B) = P(A) + P(B). ... Assume that all points are independent. |

Events A and B are independent if: knowing whether A occured
so A and C independent. Note 1: here B and C are mutually exclusive. Note 2: writing B = ”second die shows smaller number than first die ”. |
