For the given pair of events A and B, complete parts (a) and (b) below.
steposvetlana [31]

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

Answer:

681ft^2

Step-by-step explanation:

Start by finding the area of the whole thing with the missing triangle:

33 x 22 = 726

Then find the area of the triangle. You can do this by first finding out the side lengths of the triangle:

33 - 24 = 9 and 22 - 12 = 10

Then multiply both sides and divide by two because it is a triangle:

10 x 9 = 90       90/2 = 45

Then subtract the area of the triangle from the rectangle:

726 - 45 = 681
