The answer is a. to be a function there can’t be an x value that is the same to a different y value. so as an example (6,7) (3,2) (5,6) (6,3) is not a function because 6 appears 2 times as an x value but with different y values. but you can have the same y value.
Number three, because if you look at it, it is a valid one right away. Int he point (0,1), the y is one. Therefore,

y=1 is the answer.</em></u></h2>

Answer:

Step-by-step explanation:
The computation is shown below:
The numbers of possible results at the time when we drawing in two tries is 9
i.e. shown below:
11, 12, 13, 21, 22, 23, 31, 32, 33
Now the probability is

To answer the question we need to know if we replaced or not.
Lets calculate the 2 probabilities.
1, No replacement
first draw is an ace P=4/52
2nd draw is an ace P=3/51
Both are A: P=4/52 * 3/51 = 0,0045
2, With replacement
Both draws P=4/52
Both A: P =(4/52)^2 = 0,0059
So we know that it was with replacement.
This means theat the two events are independent. (both draws have 4/52 chance, not affecting eachother)
