Question

If three quarters are tossed and the numbers of heads and tails are counted,how many outcomes are possible?

Answer 1

4, if order doesn't matter

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.
