If you toss a coin three times how many possible outcomes are there?

Answer 1

In three tosses there can be four possible outcomes: three heads, three tails, two heads and one tail, and one head and two tails. ^^^That is wrong
A coin is tossed N times. There are 2 possibilities when you toss a coin: heads and tails.
So the formula is 2^N (thats to the N power)

A coin tossed 3 times has 2^3=8 possible outcomes:

head head head
head head tail
head tail head
tail head head
tail tail head
head tail tail
tail head tail
tail tail tail

There they are!
