Answer:


Step-by-step explanation:
From the question we are told that:
Sample size n=9
Number of Green 
Number of yellow 
Number of white 
Probability of Green Followed by yellow P(GY) ball


Generally the equations for when n is even is mathematically given by



Therefore



Generally the equations for when n is odd is mathematically given by



b)
Probability of drawing white ball

Therefore



Therefore
![E(y)=[E(w)-1]\frac{4}{9}](https://tex.z-dn.net/?f=E%28y%29%3D%5BE%28w%29-1%5D%5Cfrac%7B4%7D%7B9%7D)
![E(y)=[\frac{9}{2}-1]\frac{4}{9}](https://tex.z-dn.net/?f=E%28y%29%3D%5B%5Cfrac%7B9%7D%7B2%7D-1%5D%5Cfrac%7B4%7D%7B9%7D)

Answer:
x = -2 to x = 1
Step-by-step explanation:
A function is constant when the y value does not change (i.e. the graph is a horizontal line). This is true between x = -2 and x = 1.
