Answer:
X= -19
Step-by-step explanation:

Using the hypergeometric distribution, it is found that there is a 0.033 = 3.3% probability that the third red fish is the seventh fish selected.
The fishes are chosen without replacement, which means that the <u>hypergeometric distribution</u> is used to solve this question.
Hypergeometric distribution:
The parameters are:
- x is the number of successes.
- N is the size of the population.
- n is the size of the sample.
- k is the total number of desired outcomes.
In this problem:
- During the first 6 fish, we want two red.
- The seventh being red, with a 1/9 probability, as considering 2 of the first 6 are red, one of the 9 remaining will be red.
- 15 fish, thus .
- 3 are red, thus .
- 6 fish, thus .
0.033 = 3.3% probability that the third red fish is the seventh fish selected.

Hello!!
Now add them,
Therefore, the center is at the origin
(0,0), and the radius is
3. We eliminated the parameter!
Good luck :)
