Answer:
a) Binomial.
b) n=20, p=0.01, k≥2
The probability hat a package sold will be refunded is P=0.0169.
Step-by-step explanation:
a) We know that
- the defective probability is constant and independent.
- the sample size is bigger than one subject.
The most appropiate distribution to represent this random variable is the binomial.
b) The parameters are:
- Sample size (amount of clips in the package): n=20
- Probability of defective clips: p=0.01.
- number of defective clips that trigger the money-back guarantee: k≥2
The probability of the package being refunded can be calculated as:
To find the average rate of speed, divide:
1.8/0.75 = 2.4
The answer is 2.4.

The answer is 16
2.04 divided by 6 is .34 which is how much each can cost
so if you take 5.44 divided by .34 it equals 16
Pretty fast consider 115ft wasn't enough to avoid an accident..
