Step-by-step explanation:

The P(B| A) = 0.50 mean in terms of the Venn diagram is of the 4 people who have a brother, 2 of them also have a sister.

What is the experimental probability?

Experimental probability is a probability that is determined on the basis of a series of experiments.

Events are defined as follows.

Event A: The selected person has a sister

Event B: The selected person has a brother

The conditional probability of A given B is the probability that the selected person also has a sister since he has a brother.

[tex]\rm P(A|B)=\dfrac{P(A\ and \ B)}{P(B)}[/tex]

P(B) is the probability that the selected person has a brother. Notice that there are 4 people who have a brother.

P(A and B) is the probability that the selected person has a brother and also a sister. Notice that there are 2 people who have a brother and a sister.

So P(A| B) = 0.5 means that of the 4 people who have a brother, 2 of them also have a sister.

Hence, the P(B| A) = 0.50 mean in terms of the Venn diagram is of the 4 people who have a brother, 2 of them also have a sister.
