Answer:
0.11% probability that you must ask 20 people to find one person without a social networking site
Step-by-step explanation:
We have these following probabilities:
75% probability that a millenial has a profile in a social netwok site.
25% probability that a millenial does not have a profile in a social network site.
What is the probability that you must ask 20 people to find one person without a social networking site?
The first 19 people have a social network site, each with a 75% probability.
The 20th person does not have a profile, with a 25% probability.
So
![P = (0.75)^{19}*0.25 = 0.0011](https://tex.z-dn.net/?f=P%20%3D%20%280.75%29%5E%7B19%7D%2A0.25%20%3D%200.0011)
0.11% probability that you must ask 20 people to find one person without a social networking site
A statistic and a parameter are very similar. They are both descriptions of groups, like “50% of dog owners prefer X Brand dog food.” The difference between a statistic and a parameter is that statistics describe a sample. A parameter describes an entire population.
