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 times, rock & roll 171717 times, and blues 888 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. input your answers as fractions or as decimals rounded to the nearest hundredth.

Outcome     :  A(Country)    B(Rock & roll)    C(blues)

Probability  :                                              

Step-by-step explanation:

A probability model is a mathematical display of a random situation S contain various sets .

Let A be the event that they play a country music, B be the event that they play rock & roll and C be the event that they play blues.

Then , n (A) = 11, n(B)=17 and n(C)=8

Let S be the combined set of number of times music played in local restaurant.

Then ,  

Then ,

Now, the required probability model:-

Outcome     : A(Country)    B(Rock & roll)    C(blues)

Probability  :                                              

the correct answer is b. negative exponential growth.

step-by-step explanation:

you can tell it's an exponential function because it decreases rapidly then levels out and never touches the x-axis.

it is negative because the y-axis decreases as the x-axis increases.

therefore it is a negative exponential growth graph.
