Answer:

Since P(A \cap B) \neq P(A)P(B), these events are not independent.

Step-by-step explanation:

Independent events:

Two events, A and B are independent, if:

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

In this question, we have that:

P(A) = 0.4, P(B) = 0.2, P(A \cap B) = 0.1

However

P(A)P(B) = 0.4*0.02 = 0.08

Since P(A \cap B) \neq P(A)P(B), these events are not independent.

What geometric shape is modeled by a stripe on a flag
ehidna [41]

Answer:

rectangle

Step-by-step explanation:

The geometric shape that is modeled by a strip on a flag would be a rectangle. That is because just like a rectangle the shape has a total of four sides in which both parallel sides are equal in length to its matching counterpart but at the same time different from its adjacent sides. All of which are characteristics of a rectangle and at the same time found on all strips of flags.
