Answer:
30 if I divided correctly ☺
Step-by-step explanation:
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.

This is very simple.
2/4 (or 1/2) + 3/4 = 5/4 gallons of punch
Answer:
100 bags
Step-by-step explanation:
S.E = σ/ √n
0.1 = 1 / √n
Square both sides
0.1² = 1² / n
0.01 = 1 / n
0.01n = 1
n = 1 / 0.01
n = 100
