It should be A-one solution
Answer:
(a) Option A. independent
(b) ![P(A\ and\ B) = 0.0312](https://tex.z-dn.net/?f=P%28A%5C%20and%5C%20B%29%20%3D%200.0312)
Step-by-step explanation:
Two events A and B are considered dependent if the occurrence of one affects the probability of occurrence of another.
In this case, the events are independent because the birth of a girl or a boy does not affect the probability of obtaining a 1 by throwing a 16-sided die.
In the same way, throwing a die and obtaining the number 1 does not affect the probability that a baby is a girl or a boy.
When two events are independent then
![P(A\ and\ B) = P(A)*P(B)](https://tex.z-dn.net/?f=P%28A%5C%20and%5C%20B%29%20%3D%20P%28A%29%2AP%28B%29)
The probability that a baby is a girl is
![P(A) = 0.5](https://tex.z-dn.net/?f=P%28A%29%20%3D%200.5)
The probability of obtaining a 1 when casting a 16-sided die is:
![P(B) = \frac{1}{16}](https://tex.z-dn.net/?f=P%28B%29%20%3D%20%5Cfrac%7B1%7D%7B16%7D)
Then:
![P(A\ and\ B) = 0.5 * \frac{1}{16}](https://tex.z-dn.net/?f=P%28A%5C%20and%5C%20B%29%20%3D%200.5%20%2A%20%5Cfrac%7B1%7D%7B16%7D)
![P(A\ and\ B) = 0.0312](https://tex.z-dn.net/?f=P%28A%5C%20and%5C%20B%29%20%3D%200.0312)
