Question

How many possible outcomes are there when flipping a coin 9 times​

Answer 1

Answer: 512

=======================================================

Step-by-step explanation:

If you had one coin, then there are 2 outcomes because of the two sides heads or tails, which I'll shorten to H and T respectively.

With two coins, there are 2*2 = 4 outcomes (HH, HT, TH, or TT)

Having 3 coins there are 2*2*2 = 2^3 = 8 outcomes

4 coins and we have 2^4 = 2*2*2*2 = 16 outcomes

and so on

With 9 coins there are 2^9 = 512 different outcomes

Answer 2

There are 2 outcomes per flip.

Therefore the answer is 2^9 which equals 512 outcomes.
