Answer:
a. P(B|A) = P(A and B)/P(A)
Step-by-step explanation:
The notation for conditional probability is P(B|A) and is defined as P(B|A) = P(A and B)/P(A) when the two events are not independent. When the events are independent we have that P(B|A) = P(B) which means that the occurence of B does not depent of the occurence of A. Another way of define independence of two events is to say that P(A and B) = P(A)P(B). Therefore, the answer is a. P(B|A)=P(A and B)/P(A)
The notation is the probability of two events being not independent is a. [tex]P(B|A) = P(A\ and\ B)\div P(A)[/tex]
Given that,
- A and B are two events.
- The notation for conditional probability is P(B|A).
Based on the above information, the following information should be considered:
- Since we know that the notation for conditional probability is P(B|A) and is defined as [tex]P(B|A) = P(A\ and\ B)\div P(A)[/tex].
- At the time when the two events non-dependent.
- Now in the case when the events are non-dependent So it is P(B|A) = P(B) that represents that the occurrence of B does not depend to the occurrence of A.
Therefore we can conclude that the notation is the probability of two events being not independent is a. [tex]P(B|A) = P(A\ and\ B)\div P(A)[/tex]
