Suppose the average price of gasoline for a city in the United States follows a continuous uniform distribution with a lower bound of $3.50 per gallon and an upper bound of $3.80 per gallon. What is the probability a randomly chosen gas station charges between $3.70 and $3.90 per gallon?

0.333

Step-by-step explanation:

If the price of the gasoline is distributed uniformly between $3.5 and $3.8. Then the probability of a randomly chosen gas station charges between $3.70 and $3.90 per gallon is as the following:

As the upper limit of the price is only $3.8, we take into account of the random price between $3.7 and $3.8 only

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

what i would say the best answer is a. 40.5
