Prove that the probability of P(A/B)=0
Solution:
called condition probability;
If A and B are two events in a sample space S, then the conditional probability of A
A given B is defined as:
when
When A and B are disjoint they can not both occur at the same time. Thus, given that B has occurred, the probability of A must be zero. Because, when B occurred, A can not occurred.
