In most cases, I'd probably use counting technique sounds with a question.
However, it's useful to note that, when the answer choices are so small (as they are here), we should also consider the straightforward strategy of listing and counting
Let R, B, P, G and Y represent the colors Red, Blue, Purple, Green and Yellow respectively.
Now let's list the possible outcomes that meet all of the given conditions:
- RBP
- RBG
- RBY
- RPG
- RPY
- BPG
- BPY
Done!! So, there are 7 possible outcomes
Answer: A
Cheers,
