Janna, Kim s., Jon and Jessica. Question 8

Qustion 8

The question:
Jason Jolt is lending part of his art collection to the local library. He has 5 oil paintings and two water colours. The library would like to borrow two oil paintings and one watercolour. In how many different ways can Jason choose the three paintings?

The answer:
You can start by making a chart like this one below.

Oil painting #1 Oli painting #2 Oil Painting #3 Oil painting #4
op1, op2 op2, op3 op3, op4 op4, op5
op1, op3 op2, op4 op3, op5
op1, op4 op2, op5
op1, op5

Oil painting #5

(there are none in this combination because we have used them all)
There is a total of ten combinations if you just use oil paintings, but you must double that number because you have to multiply it by 2 since there are 2 watercolours. This will give you a total of 20 different combinations.
