Answer:
0.43 is the required probability.
Step-by-step explanation:
We are given the following in the question:
Number of participants that prefer Ad A = 54
Number of participants that prefer Ad B = 86
Number of participants that prefer Ad C = 60
Total number of participants =
[tex]54 + 86+ 60 = 200[/tex]
We have to find the proportion of participants preferring Ad B.
Proportion =
[tex]=\dfrac{\text{Number of participants that prefer Ad B}}{\text{Total number of participants}}\\\\=\dfrac{86}{200} = 0.43[/tex]
Thus, 0.43 is the proportion of participants preferring Ad B.
