Question

For the given pair of events A and B, complete parts (a) and (b) below.

Answer 1

Answer:

(a) Option A. independent

(b) $P(A\ and\ B) = 0.0312$

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

$P(A\ and\ B) = P(A)*P(B)$

The probability that a baby is a girl is

$P(A) = 0.5$

The probability of obtaining a 1 when casting a 16-sided die is:

$P(B) = \frac{1}{16}$

Then:

$P(A\ and\ B) = 0.5 * \frac{1}{16}$

$P(A\ and\ B) = 0.0312$
