Using the binomial distribution, it is found that there is a 0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.
For each household, there are only two possible outcomes. Either it has at least one VCR, or it does not. The probability of a household having at least one VCR is independent of any other household, which means that the binomial distribution is used to solve this question.
Binomial probability distribution
The parameters are:
- x is the number of successes.
- n is the number of trials.
- p is the probability of a success on a single trial.
In this problem:
- 14 households, hence
. - 0.535 probability of having at least one VCR, hence
.
The probability of <u>at least 6 and no more than 8</u> is:

In which:




Then:

0.5601 = 56.01% probability that the number having at least one VCR is no more than 8 but at least 6.00.

We can have 11440 different selections.
<u>SOLUTION:
</u>
Given, you have 16 different cuts of flowers
And you have planned to use seven out of them.
We have to find how many different selections of the seven flowers are possible. Now, we have to select 7 items out of 16 available items. So we have to use combinations.
Then, 7 out of 16 combination 


Hence, we can have 11440 different selections.
Using the Pythagorean theorem 4 would be the height and 8 would be the hypotenuse, you need to find the base
4^2 + X^2 = 8^2
16 x x^2 = 64
x^2 = 64-16
x^2 = 48
x = sqrt(48) = 6.92 feet ( round answer as needed )
