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

answer: there are x+184 pages in olivia's book.

step-by-step explanation:

let the total number of pages in the book which olive has already read be x.

then if olive has 184 pages left to read, then the total number of pages are in olive's book= pages she has read+pages she has left to read

therefore, the total number of pages in olivia's book=

hence, there are x+184 pages in olivia's book.
