Answer:
165 ways to choose the paintings
Step-by-step explanation:
This is clearly a Combination problem since we are selecting a few items from a group of items and the order in which we chosen the items does not matter.
The number of possible ways to choose the paintings is;
11C3 = C(11,3) = 165
C denotes the combination function. The above can be read as 11 choose 3 . The above can simply be evaluated using any modern calculator.
Step-by-step explanation:

y=1,X=1
X+y=10,2x+2y=20
