It is not a <u>probability distribution</u>, as the sum of the probabilities is more than 1, thus, the correct option is No, considering that:
c) Since the sum of the probabilities is not equal to 1.
-----------------------------------------
For the sequence representing a probability distribution, it is needed that:
- All probabilities are between 0 and 1, that is, for all values of x,
.
- The sum of all probabilities is 1, that is:
In this problem, the sum of the probabilities is:
<u>Sum is not 1,</u> thus it is not a probability distribution, and the correct option is:
c) Since the sum of the probabilities is not equal to 1.

Answer:
Step-by-step explanation:
Let be "x" the price per pound for grapefruit, "y" the price per pound for oranges.
We know that Steve buys 2 pounds of grapefruit and 3 of oranges for $7.20.
This means that the sum of the products of and
is $7.20. Then, we can write this equation to represent it:
Kennedy buys 4 pounds of grapefruit and 2 pounds of oranges for $8.80.
This means that the sum of the products of and
is $8.80. Then, we can write this equation to represent this:
Therefore, we get that the system of equations that models the situation is:
