PLEASE HELP ASAP

Which set of ordered pairs represents y as a function of x?

{(1, 3), (1, 5), (1, 7), (1, 9), (1, 11)}

{(2, 3), (3, 5), (3, -5), (-2, 8), (-2, -8)

{(1, 2), (2, 3), (3, 4), (3, 5)}

Step-by-step explanation:

in order to find a function, it needs to pass a vertical line test.

the last set of coordinates is the only one who passes the vertical line test.

44.4%

Step-by-step explanation:

The probability in this case would be the specific number of pairs of means that we are asked to calculate, that is, blue divided by the total number of pairs, which would be the sum of the different colors, then:

We have that blue there are 4 pairs, and in total it would be 2 + 4 + 3 = 9, that is to say 9 pairs of means.

therefore the probability is:

4/9 = 0.444

Which means that there is a 44.4% chance of drawing a blue pair.
