Answer:

1/6

Step-by-step explanation:

for the first marble

it might be red or blue

so   P (the first red)=4/9

then if the first one is red ,

now we have 3 red and 5 blue ,

the second one might be red again or blue

so P(the second red)= 3/8,

ok

now

P(get two red)=P(the first red) X P(the second red)=4/9x3/8=1/6

Is this figure defined by points E, F, G, and H a rectangle? Justify your answer.
Stels [109]

Answer: Second option.

Step-by-step explanation:

By definition, a Quadrilateral is a flat shape that has four straight sides.

A Rectangle is a Quadrilateral and has the following properties:

1. Its Opposite sides have the  same length.

2. All its angles have equal measure (They are congruent).

3. Each one of those angles measure 90 degrees (An angle with this measure is also known as "Right angle").

4. Its opposite sides are parallel.

5. Its opposite sides have equal lenght.

In this case you can observe that the figure defined by the points E, F, G, and H has four sides, four right angles and its opposite sides are parallel and have equal length.

Therefore, based on the above, you can conclude that it is a Rectangle.
