Question
The table above shows the results of a survey in which tablet users were asked how often they would watch video advertisements in order to access streaming content for free. Based on the table, which of the following is closest to the probability that a tablet user answered "Always," given that the tablet user did not answer "Never"?
- 0.31
- 0.38
- 0.45
- 0.69
Hint:
Hint:
- Probability is a measure of how likely an event is to happen.
The correct answer is: 0.45
Explanation:
- We have given table shows the results of a survey in which tablet users were asked how often they would watch video advertisements in order to access streaming content for free
- We have to find that which is closest to the probability that a tablet user answered “Always,” given that the tablet user did not answer “Never”.
Step 1 of 1:
The given data are
Answer
Percent
Never
31.3%
Rarely
24.3%
Often
13.5%
Always
30.9%
since the tablet user did not answer “Never,” so the tablet user could have answered only “Rarely,” “Often,” or “Always.”, the sum of all possible replies is
Thus, the possibility that a user will answer Always given only the possible options (rarely, often and always) = percentage of answering always divided by total percent of all possible answers
Hence, Option C is correct.
