We need your " thought".

We need your " thought".

A friend simply told me to add all 3 classical guitars, 3 electric guitar, and 3 pianos to find the different ways to choose an instrument.

So, 3 + 3 + 3 = 9 ways to choose an instrument at San Ash.

That was your friends thought - where is yours.

Can you distinguish between one piano from other?

Brother, the answer is 9 ways. No reason to go deeper into nonsense.
