Answer:
The probability of the tip to be more than 200 is 0.1.
Step-by-step explanation:
As per the given data
Amount of tip Number
0-20 200
20-50 100
50-100 75
100-200 75
200+ 50
____________________
Total= 500
So what is the probability of tip to be more than 200 is given as
![P(200+)=\frac{no. \, of\,occurrence}{Total\, Number}](https://tex.z-dn.net/?f=P%28200%2B%29%3D%5Cfrac%7Bno.%20%5C%2C%20of%5C%2Coccurrence%7D%7BTotal%5C%2C%20Number%7D)
From the table the value is 50 for the tip to be more than 200 where as the total occurrences are 500 so substituting values:
![P(200+)=\frac{no. \, of\,occurrence}{Total\, Number}\\P(200+)=\frac{50}{500}\\P(200+)=0.1](https://tex.z-dn.net/?f=P%28200%2B%29%3D%5Cfrac%7Bno.%20%5C%2C%20of%5C%2Coccurrence%7D%7BTotal%5C%2C%20Number%7D%5C%5CP%28200%2B%29%3D%5Cfrac%7B50%7D%7B500%7D%5C%5CP%28200%2B%29%3D0.1)
So the probability of the tip to be more than 200 is 0.1.

Answer:
200 miles
Step-by-step explanation:
63.96+(.08x)=55.96+(.12x). x=200. 63.96+(.08x200)=79.96. 55.96+(.12x200)= 79.96
Subtract tips from total:
87.05 - 50.25 = 36.80
Divide the remainder by 4.60:
36.80 / 4.60 = 8
