Hello posted picture of question can you

For a parabola if

a) Squared term is x
Parabola either opens up or down.
Positive coefficient means upward opening and negative coefficient means downward opening

b) Squared term is y
Parabola either opens right or left
Positive coefficient means rightwards opening and negative coefficient means leftwards opening

Since parabola opens right, the coefficient is positive and the squared term is y.

Therefore the possible equation of parabola is shown in option A

It is 2 out of 8 she will pick green and 3 out of 7 she will pick green but red and green would be 5 out of 5 so 50% chance

I’m having a hard time understanding your question
