C have a wonderful day and good luck with school :)
i thimk this might be the answer to question 3 (iii)
I'm sorry I don't know how to solve the first question
Answer:
20 liters of water
he will need 20 liters of water
Step-by-step explanation:
if james has 40 bottles that hold 500 milliliter then he needs 20,000 milliliters of water or 20 liters. :)
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.

I would say your answer is false because my mom works on houses and she never does this....
Hope I Helped (:
