Answer:
yes it is rational number, maybe?

Step-by-step explanation:
Since we have given that
Number of green tickets =3
Number of yellow tickets = 4
Number of purple tickets = 3
Total number of tickets = 3+4+3=10
Now,
As we know that Pedro select a ticket and replace it and then select another ticket , total number of outcomes will never change it will be 10 only for each case.
Probability that he chooses a yellow ticket and then a purple ticket is given by

Domain: (-∞, ∞), {x|x ∑ r}
Range: (-∞, 0), {y|y < 0}
Hope this helps! :)
