Abag contains 5 red marbles and 4 green marbles. what is the probability of choosing a red marble then a green marble, without replacement?

 The required probability is

Step-by-step explanation:  Given that a bag contains 5 red marbles and 4 green marbles.

We are to find the probability of choosing a red marble then a green marble, without replacement.

Total number of balls in the bag = 5 + 4 = 9.

The probability of choosing a red marble is given by

Since the second balls is chosen without replacing the first ball, so

the total number of balls remained in the bag = 4 + 4 = 8.

And the probability of choosing a green ball without replacement is

Therefore, the probability of choosing a red marble then a green marble, without replacement is given by

Thus, the required probability is

"image"

step-by-step explanation:

in most of these problems, the notation is that the point with a "prime" is the image of the point without. that is, b' is the image of b.

here, there is no dilation or reflection. there is simply translation (with no direction shown). which figure you call the "preimage" and which one you call the "image" is up to you. as a matter of convention, the naming is as described above.
