Answer:And we can use the cumulative distribution function given by:

And for this case we can write the probability like this:

And then the final answer for this case would be

Step-by-step explanation:For this case we define our random variable X “price of gasoline for a city in the USA” and we know the distribution is given by:

And for this case the density function is given by:

And we want to calculate the following probability:

And we can use the cumulative distribution function given by:

And for this case we can write the probability like this:

And then the final answer for this case would be
