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 
Answer: Here is your answer, 0.10, 0.60, 0.20, and 0.1
Step-by-step explanation:
You add up the f values and then divide them each by the value you got, which is 200. So in this case 20/200 = 0.1, and so forth. So you drag the slider up to 0.10, and do the same for each. I will send a picture with the exact answer.
The number of chicken wings that Mohal can buy is 12.
<h3>How to calculate the cost?</h3>
It should be noted that Mohal bought 20 chicken wings for $50.00. The cost of each wing will be:
= Total amount / Number of chicken wings
= $50 / 20
= $2.50
When he spent $30.00, the number of wings will be:
= Amount / Cost per wing
= $30 / $2.50
= 12
There will be 12 chicken wings. This illustrates the proportion.
