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.

What triangle I don’t see one I just see a 32?
Answer:
1/15
Step-by-step explanation:
2/3*5/5 - 3/5*3/3( we are multiplying and dividing by the same number in order to get the same denominator. as 5/5 = 1 and 3/3= 1)
2/3*5/5 - 3/5*3/3
= 10/15-9/15
= 1/15
Answer:
Below
Step-by-step explanation:
You can use the quadratic formula:
x = [-10 ± √(10^2 - 4*-1* -8)] / -2
Answer:
maximum
Step-by-step explanation:
This graph has a maximum because the parabola faces downwards. If the parabola faced upwards, then the graph would be minimum.
Hope this helps
