Answer:
The next time Mahnoor visits the restaurant, there is:
--31 % chance for country music
--47% chance of rock & roll
--22% chance of blues
Completed question;
Mahnoor randomly selects times to walk into a local restaurant and observe the type of music being played. She found that the restaurant was playing country 11 times, rock & roll 17 times, and blues 8 times. Use the observed frequencies to create a probability model for the type of music the restaurant is playing the next time Mahnoor walks in.
Explanation:
Given;
The number of times they were playing each type of music;
Country = 11 times
Roll = 17 times
Blues = 8 times
Total visits of Mahnoor = 11+17+8 = 36
Developing a frequency table and probability model for the type of music the restaurant is playing the next time Mahnoor walks in.
Probability = number of favourable outcomes รท total number of outcomes.
Music played | Frequency | Probability
country | 11 | 11/36 = .31 or 31%
rock & roll | 17 | 17/36 = .47 or 47%
blues | 8 | 8/36 = .22 or 22%
