Answer:
4, if order doesn't matter
Step-by-step explanation:
Just write them out.
You can have 3 heads: HHH
You can have two heads: HTH/HHT/THH are all the same
You can have one head: TTH/HTT/THT are all the same
You can have no heads: TTT
So this means, if the order doesn't matter, the answer is 4 outcomes.
