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

i believe it is c.y = 9x

rise over run. 9 units up over 1 unit right or 9/1
