In a recent survey by The Hollywood Reporter, a random sample of adults aged 18-29 were asked the following question:
How often do you listen to music via streaming services?
Response | Every day | Several times per week | About once per week | Several times per month | About once per month | Less than once per month | Never |
Probability | 0.51 | 0.19 | 0.05 | 0.04 | 0.01 | 0.05 |
Find the probability for the "Never" response.
What is the probability of “Less than once per month” or “Never”?
A music lover listens to streaming music several times per week or more. Find the probability of getting someone who is a music lover.
A music lover listens to streaming music several times per week or more. Find the probability of getting someone who is NOT a music lover.
A music lover listens to streaming music several times per week or more. Given that someone is a music lover, what is the probability that they listen to music every day?
Find the totals for the two-way table.
| Avid Fan | Casual Fan | Not a Fan | Total |
Gen Z: Age 18-22 | 107 | 41 | 13 | |
Millennial: Age 23-38 | 401 | 213 | 32 | |
Gen X: Age 39-54 | 307 | 226 | 24 | |
Boomers: Age 55-73 | 281 | 397 | 49 | |
Total | | |
Suppose we randomly select one of these adults. What is the probability that they are a casual fan?
Suppose we randomly select one of these adults. What is the probability that they are not an avid fan?
Suppose we randomly select one of these adults. What is the probability that they are a Boomer who is not a fan?
Suppose we randomly select one of these adults. What is the probability they are Gen Z or an avid fan?
Suppose we randomly select one of these adults. What is the probability that they are an avid fan if we know that they are a Millennial?
Suppose we randomly select one of these adults. Given that they are 39 or older, what is the probability they are an avid fan?
