.5 or 1/2
As a coin has two sides, the odds are always 50-50.
None, since that would imply that in 18 cases the coin did not show heads or tails!
The probability of NOT getting heads is (1/2)4=1/16 Therefore the probability of getting heads is 1-1/16=15/16
Heads - ½ Tails - ½ There are two reasonable outcomes of flipping a coin. You could get heads or tails. Some might argue that the third outcome is that the coin will land on the edge.
The event is that the coin lands with the Heads on top.
The probability of flipping a coin 3 times and getting 3 heads is 1/2
There are 8 permutations of flipping a coin 3 times, or of flipping 3 coins one time. They are, with the permutations of two heads bolded...TTTTTHTHTTHHHTTHTHHHTHHH... thus, the probability of flipping a coin 3 times and getting 2 heads is 3 in 8, or 0.375.

As a coin has two sides, the odds are always 50-50.
The sample space when flipping a coin is [heads, tails].
The probability of this is 50%. 2/4

You still still have a 1:2 chance of getting heads regardless of the times you flip.
