Answer:
(4, 6)
Step-by-step explanation:
The second point is 8 units up from the first, so its y-coordinate is 8 more than -2. Its x-coordinate is unchanged. Its location on the grid is (4, 6).
_____
(4, -2) +(0, 8) = (4, 6)
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.
