Question

how many different sequences of heads or tails are possible if a coin is flipped 8 times?

Answer 1

each time you flip it you have to multiply the number of possible outcomes by 2
1 flip = 2 sequences (just a head or a tail)
2 flip = 2 x 2 = 4 sequences
3 flips = 2 x 2 x 2 = 8 sequences
...
therefore 8 flips = 2 x 2 x 2 x 2 x 2 x 2 x 2 x 2 = ?
