Which shape could be thought of as being created by stacking congruent polygons
Colt1911 [192]

When they talk about congruent polygons, they meant geometric figures that are all equal in shape and size.

It's angled, and the side length is equal too.

When you piled equal polygons, you'll end up with what we call prisms. It's the 3D form of a polygon.

If you stack squares, you'll have a cube.

If you stack octagons, you'll have an octagon prism.

If events A and B are independent, what must be true?A.) P(AB) = P(B)
anygoal [31]

Answer:

B.) P(A/B) = P(A)

Step-by-step explanation:

If two events, A and B are independent:

We have that:

P(A \cap B) = P(A)P(B)

Conditional Probability

We use the conditional probability formula to solve this question. It is

P(B|A) = \frac{P(A \cap B)}{P(A)}

In which

P(B|A) is the probability of event B happening, given that A happened.

P(A \cap B) is the probability of both A and B happening.

P(A) is the probability of A happening.

Since they are independent:

P(A \cap B) = P(A)P(B)

Then

P(B|A) = \frac{P(A \cap B)}{P(A)} = \frac{P(A)P(B)}{P(A)} = P(B)

So

P(B|A) = P(B), or either:

P(A|B) = P(A), and thus, the correct answer is given by option B.
