Can someone answer the following question?
Data collected by a major cell phone provider indicate that only 20% of cell phone customers are willing to switch cell phone providers. If a binomial process is assumed, then in a sample of 20 cell phone customers find the following probabilities:
|
0.0115 |
|
0.6826 |
|
0.1234 |
|
0.3678 |
|
0.0001 |
|
0.5793 |
|
0.9994 |
|
0.4110 |
What is the probability that no more than 3 customers would be willing to switch their cell phone provider?
What is the probability that 12 or more will be switching their cell phone provider?
What is the probability that between 5 and 9 (including 5 and 9) will be switching their cell phone provider
What is the probability that no one will be switching their cell phone provider?
What is the probability that 10 or fewer will be switching their cell phone provider?
