Step-by-step explanation:
Given




Solving (a): 
This is calculated as:


Solving (b): 
This is calculated as:
-- this is so because the selection is without replacement



Solving (c): 
Using the complement rule, we have:

To calculate
, we have:
--- Green
---- Not green
The probability that both selections are not green is:

So, we have:



Simplify
