Using the hypergeometric distribution, it is found that there is a 0.7568 = 75.68% probability that neither can wiggle his or her ears.
The people are chosen from the sample without replacement, which is why 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:
- 1000 people means that
- 130 can wiggle their ears, thus
- Two are selected, thus
.
The probability that neither can wiggle his or her ears is P(X = 0), thus:
0.7568 = 75.68% probability that neither can wiggle his or her ears.

Answer:
60%
Step-by-step explanation:
There was a total of 3000 people and of those 3000 people only 18 had a mild allergic reaction.
18/3000 × 100 = 60%
<span>Carla is renting a canoe. It’s cost $80 for 2 hours and $160 for 4 hours. What is the rate per hour?
If we want to get a full understanding of this question we must use the information given.
If renting the canoe cost $80 per 2 hours, to get 1 hour we must divide $80 by 2.
</span>
or $40
We can also use $160 and 4 hours
or $40
So the rate per hour is $40
